glupload: Use base class metadata copy function

This allow properly copying selected meta, like the composition
overlay. Note that output buffer need to be readable, but GlUpload
keeps a ref. For now, simply drop GlUpload ref after perform,
leaving that ref has no purpose. The method shall be removed
in the future.
