check for errno==EAFNOSUPPORT

Default build of nmap-7.40 package does not work for kernels build without INET6 support:

# nmap -dd --iflist

Starting Nmap 7.40 ( https://nmap.org ) at 2017-03-05 16:45 +07
Fetchfile found /usr/local/share/nmap/nmap-services
PORTS: Using top 1000 ports found open (TCP:1000, UDP:0, SCTP:0)
INTERFACES: NONE FOUND(!)
Reason: getinterfaces_dnet: intf_open() failed
ROUTES: NONE FOUND(!)
Reason: getsysroutes_dnet: sysroutes_dnet_find_interfaces() failed

One-line attached patch fixes this so mentioned command works for INET4-only kernel and also "nmap -sS" and others.
Comment 1 Eugene Grosbein 2017-03-05 09:54:37 UTC 
Also a comment:

# Note: nmap does no longer build agains custom kernel without IPv6!

in port's Makefile should be removed as it does build against custom kernel without IPv6. And works with supplied patch applied.
