As for compiling syscalls.S needed syscall-aux.h header,
which is linked with making $(sys-asm-types), add it to deps.

The objective is to only do parasite code linking once -- when we link
parasite objects with compel plugin(s). So, let's use ar (rather than
ld) here. This way we'll have a single ld invocation with the proper
flags (from compel ldflags) etc.
There are two tricks in doing it:
1. The order of objects while linking is important. Therefore, compel
plugins should be the last to add to ld command line.
2. Somehow ld doesn't want to include parasite-head.o in the output
(probably because no one else references it), so we have to force
it in with the modification to our linker scripts.
NB: compel makefiles are still a big mess, but I'll get there.

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
