Fix related to T65963: Ctest: Failing test script_load_keymap passes.

Fix things to make test actually fail as expected (one cannot compare
functions to strings, so no more sorting for now).

Not sure how to actually fix the test though, not even sure test make
any sense anymore actually, with all those weirdo gizmos and tools
keymaps thingy...
