kselftest: fix TAP output for skipped tests

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).
