[POWERPC] Switch to generic compat_binfmt_elf code

This switches the CONFIG_PPC64 support for 32-bit ELF to use the generic fs/compat_binfmt_elf.c implementation instead of our own binfmt_elf32.c. Since so much is the same between 32/64, there is only one macro we have to define to make the generic support work out of the box.
