objtool/klp: Create empty checksum sections for function-less object files

If an object file has no functions, objtool has nothing to checksum, so
it doesn't create the .discard.sym_checksum symbol.

Then when 'objtool klp diff' reads symbol checksums, it errors out due
to the missing .discard.sym_checksum section.

Instead, just create an empty checksum section to signal to
read_sym_checksums() that the file has been processed.
