services: nginx: Get the Shepherd to respawn NGINX.
* gnu/services/web.scm (nginx-shepherd-service): Change 'start' (that is, all
actions that don't send a signal to the master process) to return the PID.
Wait until the PID file is created and contains an integer because it might be
created after the parent process exits.
