Commit 0ef67a888375 ("selftests/harness: Report skip reason")
added shared memory to communicate between harness and test.
Use that instead of exit codes to send the failing step back
to the harness. The exit codes are limited and because of
the step passing we can't use the full range of KSFT_* ex
Hi!
When running selftests for our subsystem in our CI we'd like all
tests to pass. Currently some tests use SKIP for cases they
expect to fail, because the kselftest_harness limits the return
codes to pass/fail/skip.
Clean up and support the use of the full range of ksft exit codes
under kselfte
Now that we no longer need low exit codes to communicate
assertion steps - use normal KSFT exit codes.

Selftest summary includes XFAIL but there's no way to use
it from within the harness. Support it in a similar way to skip.
Currently tests report skip for things they expect to fail

This is confusing because in an ideal environm
