linux-user/ppc: use the Linux register layout 

The dynamic linker converts the Linux layout to the AIX layout and is
reentrant so it won't do it a second time if it's already been
converted. In short it work just fine with either register layout.

OTOH, statically linked binaries expect a Linux layout.

Remove code converting the Linux layout to AIX layout so that all
binaries are presented the Linux Layout.
