According to the TAP specification, a skipped test must be marked as "ok" and annotated with the SKIP directive, for example
ok 23 # skip Insufficient flogiston pressure. (https://testanything.org/tap-specification.html)
Fix the kselftest infrastructure to match this.
For ksft_exit_skip, it is preferrable to emit a dummy plan line that indicates the whole test was skipped, but this is not always possible because of ksft_exit_skip being used as a "shortcut" by the tests. In that case, print the test counts and a normal "ok" line. The format is now the same independent of whether msg is NULL or not (but it is never NULL in any caller right now).
