pcap-file: Flush packets to operating system immediately.
This makes the pcap files written by netdev-dummy up-to-date even if one
kills the process with a signal. This could be a performance hit if
the pcap file writer were to be used in some kind of performance critical
situation, but so far it's only used in netdev-dummy, which is just for
testing.
