Define the exit codes with KSFT_PASS and similar so tests can use these
directly if they choose. Also enable harnesses and other tooling to use
the defines instead of hardcoding the return codes.

Am I the only person who's bothered by the fact that these don't actually
return int?

That bothered me to, but I couldn't be bothered to go read the manuals
apparently to come up with a compelling argument :-)

Yeah, obviously the compiler accepts it, but it's still a bit weird.

I also think the ksft_exit* routines should go ahead and increment the
counters (at least optionally) so we don't have to call two functions.

But the ksft_exit_*() routines exit, so there's no point incrementing the
counters. Unless they *also* print the counters before exiting?

To be honest I think we need to decide if the selftests are going to speak TAP
or xUnit or whatever, and then switch to that. In their current form these
helpers don't help much.
