plugins: modify image check of extract_allowed_surface_formats.

Browse source 
The extract_allowed_surface_formats function just check whether
we can support some kind of surface/image format pair. We just
need to create a surface, create an image with the same video-format
and putImage from image to surface. All these operations success,
that kind of video-format is supported.
The old manner do not work for some kind of video-format. For example,
the RGBA kind of format will create a NV12 surface and RGBA image,
and the putImage will fail because the format is not same. And so
the RGBA format is not supported but actually it is supported.
