[PATCH] selftests/harness: harness-selftest: cover XFAIL_ADD ctor ordering

[Sun Jian <sun.jian.kdev@gmail.com>]

Add a fixture-based test with a single variant and mark it with
XFAIL_ADD(). The test intentionally fails and is expected to be
accounted as XFAIL, covering the constructor ordering dependency
between TEST_F() registration and XFAIL_ADD() registration.
