BACKPORT: arch: wire-up clone3() syscall

Browse Source 
Wire up the clone3() call on all arches that don't require hand-rolled
assembly.

Some of the arches look like they need special assembly massaging and it is
probably smarter if the appropriate arch maintainers would do the actual
wiring. Arches that are wired-up are:
- x86{_32,64}
- arm{64}
