syscall: remove linknames to runtime symbols for aix/ppc64
Replaces //go:linkname by assembly functions for syscall
functions on aix/ppc64.
Since the new runtime internal ABI, this was triggering an error if
syscall.Syscall6 was called by others packages like x/sys/unix.
This commit should remove every future occurences of this problem.
Fixes #28769
