Subject: [RFC][PATCH 2/5] objtool: Move struct objtool_file into arch-independent header

The objtool_file structure describing the files objtool works on is
not architecture dependent -- it's not x86 only -- and it will be useful
for any future commands that might not be part of the check / orc
tooling. So we move it from the check.h header  into the objtool.h header.
