3fda54ece8 IHK: support for using Linux work IRQ as IKC interrupt (optional)

dfb3bef96d irqbalance_mck: replace extra service with service drop-in
Using a drop-in instead of an extra service avoids having to juggle
between both services (especially since irqbalance_mck did not have a
Conflict=irqbalance.service statement)

That way, we only have a single service to check for (irqbalance.service),
and system administrators should find this less confusing if they normally
rely on irqbalance.

The drop-in is also installed in /run so will automatically disappear in
the event of a linux crash or a reboot without shutting down mckernel

791e8c2114 Remove mcoverlayfs code
mcoverlayfs code is now unused (technically should work on top of the
soft emulation but not well tested, and untested unused code is bad).
Remove it.

Left the unshare/bind_mount_recursive code in mcexec in a new
MCEXEC_BIND_MOUNT ifdef (only in config.h.in directly to discourage use.
it disables the ioctl as well, but the main code is still compiled to
keep up to date with linux api changes... although it's using kallsyms
lookup so it does not validate much more than "the symbol still exists")

I honestly think this should go as well (people who would want to use it
are root and could do it manually), but will give up for now.

b87ac8b8c0 reproductible builds: remove most install paths in c code
In order to speed up test bot work it would be helpful to check for
identical build outputs and skip tests if required.

This removes most use of the install path in c code:
 - ql_mpi uses /proc/self/exe and looks for talker/server in same
directory as itself
 - mcexec looks for libihk.so in /proc/self/maps and use that path for
LD_PRELOAD prefix path
 - rootfsdir is not used right now but until a better fix happens just
hardcode it, someone who wants to change it can set it through cmake

There is one last occurence of the install directory, MCEXEC_PATH in
mcctrl's binfmt code, for which the build system will just overwrite it
to a constant string at build time instead of trying to remove it too
hard. It would be possible to pass it as a kernel parameter or look for
mcexec in PATH but this is too much work for now.

ccb36a5849 cmake: change how warning flags are added
Setting CMAKE_C_FLAGS_DEBUG does not work as first expected:
 - set(... CACHE) didn't do anything because the variables were
initialized previously
 - We could set with FORCE but then users could not change the value
 - There is a way to only do that on initial cmake run but it has the
same problem

Thus, use a new regular cache variable directly instead

6a456f11aa cmake: remove unused build-time symbol lookup
Everything already uses kallsyms_lookup_name or similar, this
was leftover from when the build system was ported ages ago

fb3f1c58a8 rpm: ignore CMakeCache.txt in dist and relax BuildRequires on cross build
CPack takes the source dir as is, so if it was used to build something
it will incorrectly grab the temporary CMakeCache file and cmake will
complain during rpmbuild later on.

The BuildRequires should be a separate patch but logic behind the change
is that the dependencies need to be installed in the sysroot, and
rpmbuild cannot test this, so just move them all to only enforce
BuildRequires for native build.

And while we are here, also add a new kernel_dir specfile option.

54122360e8 CMake: move CONFIG_ARM64_64K_PAGES and VA_BITS up to main CMakeLists
user code also needs these defines; there was a hard-coded
definition left out from debugging that didn't get cleaned up
