nmap loopback patch (DLT_LOOP 12/108)

[Daniel Hartmeier <daniel_(_at_)_benzedrine_(_dot_)_cx>]

The -current nmap port requires the patch below to work on loopback, try

  # nmap 127.0.0.1

The comment just above the #define DLT_LOOP seems to suggest this, but I
don't see why Fyodor isn't just doing it himself, like in the DLT_ENC
case just below.
