mnet: restore_create_users() is now mnet-aware

Browse Source 
It will now default to $CFG->mnet_localhost_id and can
handle backup files containing an mnethosturl user property
which will be mapped to mnethostid.

Additional checks are needed to avoid restoring files
with mnethosturls we cannot handle.
