Fix multilayer OpenEXR not supporting metadata. 

This will fix exporting of metadata and importing for imbufs, but image
editor will not display these metadata since multilayer gets converted
to renderresult, which does not support metadata display yet.
This commit is more meant for external image editors/viewers.
