Don't map resource objects.

For one, they generally have a base address of 0x0, but also, we're probably
going to load/parse these into a hashtable somewhere in the loader
and use that for resource lookups instead of parsing LX binaries during
DosGetResource(), and that is more of a malloc() thing than an mmap() thing.
