media: vivid: always allow meta output streaming

The vivid metadata output emulation only works if the
video input is configured for a webcam. That makes no sense,
and it is in fact a copy-and-paste from the metadata capture
support.

Always allow metadata output, just make sure that when the
metadata is processed it only sets the brightness/saturation/
hue/contrast controls if they have been defined: if vivid was
instantiation without video capture support, then those controls
are missing.

This change ensures that the test-media regression script correctly
tests metadata output streaming.
