SEGFAULT in pcap_findalldevs on OpenBSD 3.4

pcap_findalldevs dies on OpenBSD 3.4 while interpreting some of the data
returned by getifaddrs.  Specifically, the flag value suggests that a
Broadcast address is provided, but none is really returned.

This problem does not exist on FreeBSD or NetBSD.

The attached patch seems to safely fix the issue.
