Add ENETUNREACH to the list of known error codes in service_scan.

Browse source 
Nathan Stocks reported the crash:
Unexpected error in NSE_TYPE_READ callback.  Error code: 101 (Network is unreachable)
It was traced to a middlebox sending admin-prohibited messages, which
were surfacing in the socket API as ENETUNREACH.

Compare to r17488, which added EPROTO.

// That is funny. The port scanner listed the port as open. Maybe it got unplugged, or firewalled us, or did
// something else nasty during the scan. Shrug. I'll give up on this port
