UI: Fix incorrect properties set for Hardware (AMD)

Due to an oversight in enc-amf with strcmp, the code currently causes
certain weirdness to appear.  This fixes it so it will use "High"
Profile instead of attempting to use "Constrained Baseline" and also
changes it to actually set things up for "Constant Bitrate" instead of
"Variable Bitrate (Latency Constrained)".  Finally I've added a slight
change that always makes it set the B-Frame Pattern to 0 in order to
work better with VCE2.0 and VCE3.0 cards.

Closes jp9000/obs-studio#978
