gmap_location.install conflicts with location.install

The gmap_location.install file installs its own version of the location table. This causes conflicts with the location module, which gmap_location requires. I believe this is a hold over from when gmap_location was a fork of location.

This patch removes the offending table definitions from the install hook. It leaves the updates in place. I'll let someone else decide if they want to remove those.
