Replace legacy vaapih264enc with vah264enc

Browse Source 
The gstreamer-vaapi plugin suite (vaapih264enc) is superseded by the va
plugin (vah264enc) in gst-plugins-bad. Switch to it and update the
parameters accordingly: CBR instead of VBR for lower-latency streaming,
key-int-max instead of keyframe-period, and target-usage instead of
quality-level.
