video/image_writer: avoid stripping colorspace info when writing image 

Writing an image either with vo_image or with a screenshot will strip
the colorspace info because it allocates a new mp_image that contains
the same data as the old image after calling mp_image_params_guess_csp.
However, mp_image_params_guess_csp cannot always guess the appropriate
colorspace, so it picks a "sane default." Since this function also
changes parameters so the space always makes sense, this extra info
isn't harmful and allows screenshots and vo_image outs to be properly
tagged with the correct colorspace.

Fixes #10988.
