Avoid warnings from nwfilter driver when run non-root
When run non-root the nwfilter driver logs error messages about being unable to find iptables/ebtables commands (they are in /sbin which isn't in $PATH). The nwfilter driver can't ever work as non-root, so simply skip it entirely thus avoiding the error messages * src/conf/nwfilter_conf.h, src/nwfilter/nwfilter_driver.c, src/nwfilter/nwfilter_gentech_driver.c, src/nwfilter/nwfilter_gentech_driver.h: Pass 'bool privileged' flag down to final driver impl * src/nwfilter/nwfilter_ebiptables_driver.c: Skip initialization if not privileged
