objtool/klp: Add test for recorded checksum values
Whether klp diff treats a function as changed is decided by its checksum,
and until now nothing looked at one. A test asserting only that the right
functions were cloned cannot tell a correct checksum from one that happens
to differ.
Asserts both directions -- the changed function's checksum moves, the
untouched one's does not -- and that checksumming identical input twice
gives the same answer, since otherwise every rebuild reports spurious
changes.
