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.
