Add the Solaris "any" device in pcap_findalldevs() if we have it.

There's no good run-time test, so we test at configure time, by checking
whether /usr/include/inet/ipnet.h exists and contains IPNET_ANY_LINK.
See https://github.com/the-tcpdump-group/tcpdump/issues/1057#issuecomment-1584088911

We make a common routine to use to add that device.
