Update FreeBSD elf_common.h.
Looks like I'd been bad here, and added new stuff to this file rather
than <elf.h> directly. I've also done nothing to upstream any of this.
This patch at least addresses the former problem, moving our stuff out
into <elf.h>.
Rather than *delete* anything that conflicts with Linux in elf_common.h,
I've disable it with // or #if, and marked those as Android changes to
make it less likely that the next update accidentally drops them (which
isn't super likely, since most of them should actually cause build
failures when they conflict with uapi).
Test: treehugger
