Qt: Add the "Map" button to the Endpoints dialog.

Move the map creation code from ui/gtk/hostlist_table.c to
ui/traffic_table_ui.c.

Add CMake commands to copy ipmap.html to the run directory so that
WIRESHARK_RUN_FROM_BUILD_DIRECTORY works for the endpoint map. Not sure
if they're entirely correct but they appear to work.

Add boundary checkes to geoip_db_lookup_ipv[46].

To do:

- It looks like there are prettier maps and newer APIs that we
  might want to use.
