rS350587: [PPC64] Fix rtld direct exec mode

Summary

Instead of restoring the saved values of argc, argv and envp,
these must be loaded from the stack that _rtld() modifies.

This fixes rtld direct exec mode.
E.g.: /libexec/ld-elf.so.1 /bin/ls

A brief look at powerpc/rtld_start.S code seems to indicate that the same changes apply to powerpc.

But it would be better for someone with 32-bit powerpc hardware to make the change and confirm it works fine.
