add mime data to soft masked images

The cairo backend is not currently setting the mime data for soft masked images. As a result jpeg images are Flate encoded in PDF output resulting in increased file size.

The attached patch fixes this.

The PDF test case I used is:
https://bugzilla.gnome.org/attachment.cgi?id=163460
from bug https://bugzilla.gnome.org/show_bug.cgi?id=621359

This has a file size of 84K. When printed to PDF using cairo the file size is 253K. After applying this patch the file size is 45K.
