[PATCH v4 3/7] kselftest/alsa: pcm - Always run the default set of tests

[Mark Brown]

Rather than allowing the system specific tests to replace the default set
of tests instead run them in addition to the standard set of tests. In
order to avoid name collisions in the reported tests we add an additional
test class element to the reported tests. Doing this means we always get a
consistent baseline of coverage no matter what card we run on but retain
the ability to specify specific coverage for a given system.
