This is due to Tahoe-LAFS not finding ifconfig.

Hey, we ought to make this error message clearer and ask the person
seeing it to describe their platform's "ifconfig" to us. There: #1536

This is due to Linux's major version number going from 2 to 3. Here is
a patch to let tahoe-lafs handle with this correctly.

In addition there are a couple of tests which need to be updated:
