vapoursynth: Don't update script colorspace if colorspace unknown

Browse source 
Aegisub will automatically override the YCbCr Matrix field of the
current file's Script Properties with the video's reported color space.
The FFMS2 provider guesses a color space for all videos, but we don't
do this for Vapoursynth. Thus, we now disable this overriding whenever
the colorspace isn't known.
