Fix deletion of routing policy rules when terminating due to a signal

This patch fix routing policy rules not being deleted on termination
due to SIGTERM, SIGHUP, SIGUSR1 or SIGUSR2.
Calling uloop_end makes the call to uloop_run on main to finish and
the process to exit calling the proper cleaning functions.
