[sustrik]

All other services are named something like br1-ff00_0_222.
SIG is nmaed sig_1-ff00_0_222. This patch makes the naming consistent.

That implies changing more stuff (network names?) Frankly, I don't understand topology generator well enough to say what should and what should not be changed.

As discussed it is fine if we just change the sig name.
