vaapih264enc: propose new profile caps and fixate it

Browse source 
When the available caps doesn't intersect with the allowed caps in the
pipeline, a new caps is proposed rather than just expecting to
iterate.

Later, the intersected caps (profile_caps) is fixated in order to
extract the configuration.
