From Max Laier: check whether the system has <net/pfvar.h> and:

	if it does, use that for the pf definitions;

	if it doesn't, don't compile in pf support;

as both OpenBSD and FreeBSD have changed the pf definitions and header
format without changing the DLT value, so you can't reliably read
pflog-format libpcap files on a machine running an OS version other than
the one on which the file was generated.
