fff-uradvd: Add reload trigger for network

fff-uradvd depends on values stored in the uci network config.
Therefore, a reload is required if the uci network config is modified.

As fff-uradvd does not support reloads, and possibly changing values are
given as command parameters, do a restart on procd reload.
