Subject: GOB: Work around broken resource sizes in Gobliiins EGA

The EGA version of Gobliiins, similar to Little Red Riding Hood,
claims a few resources are larger than they actually are. The original
happily reads past the resource structure, but we'll instead fix
the size of the resource after loading.

This fixes bug #7162.
