kunit: tool: Parse skipped tests from kselftest.h

Skipped tests reported by kselftest.h use a different format than KTAP,
there is no explicit test name. Normally the test name is part of the
free-form string after the SKIP keyword:

	ok 3 # SKIP test: some reason

Extend the parser to handle those correctly. Use the free-form string as
test name instead.
