lavc/tiff: Enable decoding of LinearRaw images

Browse Source 
"LinearRaw" is a value that the PhotometricInterpretation tag can be set
to on DNG images that contain color information for all channels instead
of being bayer-encoded ("CFA" value).

The DNG decoder is complete enough that we can enable this now.
