sd-event: permit a USEC_INFINITY timeout as an alternative to a disabling an event source
This should simplify handling of time events in clients and is in-line with the USEC_INFINITY macro we already have.
This way setting a timeout to 0 indicates "elapse immediately", and a timeout of USEC_INFINITY "elapse never".
