diald 2.0.x kernel patch

[Dominic Amann]

Here is patch neccesary to those of us kernel "version challenged"
folks who do not have AF_PACKET support (2.0.x kernels), which
affects the firewall checking stuff in firewall.c:

It removes a feature from the package, but probably we cannot
have the feature anyway? And the package now compiles whereas
it would not before, and my dial setup still works after installing
it.
