This firewall was introduced as a countermeasure for very slow routers
directly connected to the internet without any firewall.
Our routers have got quite a bit faster since then. Also, a setup like
this is highly uncommon, especially for slower routers.
Therefore this firewall rule is removed.
Fixes: #138

In some cases (mostly for one-port devices) IF_WAN was used
although not set, resulting in not obviously iptables error
messages like
- Bad argument `conntrack'
- Bad argument `REJECT'
Thus, check whether IF_WAN is set to something before using it.

The syntax " -m state --state " seems to be not supported anymore.
The replace should not change behavior compared to
lede-17.01-based firmware.
Added required dependency.
