obs-x264: Fix color space/range not being set

I originally had it set the color space and color range in the video
info callback, but I forgot that it's a function that's called after the
encoder is initialized.  You can change the color space and color range,
but you have to reconfigure the encoder, and there's no real reason to
do that.
