[media] uvcvideo: Mark first output terminal as default video node

Browse Source 
The MEDIA_ENT_FL_DEFAULT identifies entities that are considered as
default for their group and type. For video nodes, it identifies the
node that application should use by default.
UVC devices don't report which output terminal should be considered as
the default, use the first one. Most devices have a single output
terminal anyway.
