glamor: Make sure Xvideo source image data is properly aligned

Browse Source 
_glamor_upload_bits_to_pixmap_texture currently ignores the stride
parameter, but __glamor_upload_pixmap_to_texture uses 4-byte alignment
via glPixelStorei(GL_UNPACK_ALIGNMENT, 4).

Also fix up the stride argument passed in though, in case it starts
being used properly in the future.
