Lynn Boger 7155702f2d unix: fix errors in syscalls when using -linkshared on ppc64x
When using -linkshared, the external linker on ppc64x cannot
always handle the direct branch to syscall.Syscall and similar
similar functions when the offset is too far. Instead it should
be done as a BL which can then be called through a procedure
linkage table entry.

This change removes functions Syscall, Syscall6,
RawSyscall, RawSyscall6 from asm_linux_ppc64x.s and instead
creates Go functions which call their corresponding
functions in the syscall package. As Go functions, they can be
inlined with the help of CL 147361.

Fixes golang/go#16662
