And use it in CRIU directly instead:

 - move syscalls into compel/arch/ARCH/plugins/std/syscalls
 - drop old symlinks
 - no build for 32bit on x86 as expected
 - use std.built-in.o inside criu directly (compel_main stub)
 - drop syscalls on x86 criu directory, I copied them already
   in first compel commist, so we can't move them now, but
   delete in place
