res_pjsip_outbound_registration.c: Use ast_sorcery_object_unregister() API
The sorcery pjsip 'registration' config object needs to be destroyed on
module unload. Otherwise, a reload of res_pjsip could try to use
callbacks for a previously unloaded instance of the module provided by
ast_sorcery_object_register() or one of the variants. Also, if
res_pjsip_outbound_registration were subsequently reloaded, the sorcery
config field objects would be registered in sorcery twice.
