[jcifs] InetAddress.getLocalHost easily fails and causes an NPE in NbtAddress

[Michael B Allen]

This NPE has been fixed in 1.2.18 to be released RSN.

Note that this the fix doesn't actually come up with the correct local
host address. If InetAddress.getLocalHost throws an exception there's no
way to determine the localhost. It's basically a host config issue. The
"fix" is to use an InetAddress of 127.0.0.1 which means some things may
not work correctly (although it might help to set the 'laddr'
properties).
