mcoverlayfs: update and compile new overlayfs for 4.18 kernels

Browse Source 
This newer version is much simpler than the old ones:
 - the options are noop, this lets the code simplify all the allocating
of a new option struct and passing it around
 - ovl_reset_ovl_entry was added and called all the time, but the
mechanism that made this required is gone in this kernel version

On the other hand, one new thing in this version:
 - newer kernel check the stacking depth of filesystems now, and we are
reaching the default limit of two with our setup. Bump it to three here.

Also, while we are here, make make fail if requested directory does not
exist, instead of infinitely recurse into make modules in the mcoverlayfs
directory...
