uvch264: Add a fakesink to the transform_caps

Browse Source 
Some version of basetransform will return the template caps if the src
pad is not linked, so the capsfilter will return ANY. Linking it to
fakesink allows us to return the right caps in the capsfilter and have
them transformed by the colorspace converter.
