unix/linux: unify ppc64x syscall wrappers

CL 146518 (commit 7155702f) attempted to fix a linker
limitation by using native go. This resulted in some
very hard to uncover issues noted in golang/go#81981.

Reintroduce the asm, but use an indirect jump to avoid
linker generated trampolines.

Fixes golang/go#81981
