kselftest/alsa: pcm - skip tests when we fail to set params

Since we don't know what the capabilities of an unknown card is any of our
standard tests may fail due to not being supported by the system. Set a
flag once we've configured the stream, just before we start data, to say
that the system accepted our stream configuration.

Since there shouldn't be a use case for tests that are specified for the
individual system failing for those tests we also add a new test which
fails if we are unable to configure the settings specified in the system
specific configuration file.
