If MTE is not available on a system, we detect this early and skip all
the MTE selftests. However this happens before we print the TAP plan, so
tools parsing the TAP output get confused and report an error.

Use the existing ksft_exit_skip() function to handle this, which uses a
dummy plan to work with tools expecting proper TAP syntax, as described
in the TAP specification.
