obs-ffmpeg: Fix wrong framerate in AMF VUI header

Frame rate should be defined before AMF encoder initialization,
because this information is used for setting vui_time_scale in SPS.
If frame rate isn't defined before initialization,
then AMF encoder set default frame rate into VUI header (30 fps).
