swscale/swscale_unscaled: fix planarCopyWrapper() for yuv444p => yuva444p
Currently, planarCopyWrapper() assumes that src[3] must be NULL when
the source format has no alpha plane.
This commit updates the condition for filling the alpha plane based on
the number of components available in the source format as well.
