vaapipostproc: update filter before fixate caps

Browse source 
It is requiered to know if postproc is capable to change the video
direction before fixating the source caps.

In order to do it, it'ss required to know if there's a functional VPP,
but that's checked at create() vmethod, which occurs after caps
fixating.

This patch checks for a functional VPP at fixate caps and, if so,
checks for the enabled filtes and later do the caps fixations.
