output: elf -- Move common structures into outelf.h header

All Elf formats we're supporting at the moment have
are using same structures, move them into a header
and name then with elf_ prefix.

This makes a few fields to carry 64 bit integers while
in former Elf32|x formats they can be 32 bit wide, but
I think it's acceptable tradeoff.
