[RFC][PATCH 02/36] objtool: Move struct objtool_file into arch-independent header

[Matt Helsley]

The objtool_file structure describing the files objtool works on is
not architecture dependent -- it's not x86 only. So we can split it
out from the check.h header that will move into arch/x86 and reuse
it for future objtool subcommands.
