linux-user: Move get_elf_platform to arm/elfload.c

Browse Source 
Move the aarch32 get_elf_platform to arm/elfload.c; pass in CPUState.
Create a simple version in aarch64/elfload.c, which we must do at the
same time because of the ifdef dependency between TARGET_AARCH64
and TARGET_ARM.

Since all versions of get_elf_platform now have the same
signature, remove the ifdef from the declaration in loader.h.
