net: No longer send local address in addrMe

Browse Source 
After #8594 the addrFrom sent by a node is not used anymore at all,
so don't bother sending it.

Also mitigates the privacy issue in (#8616). It doesn't completely solve
the issue as GetLocalAddress is also called in AdvertiseLocal, but at
least when advertising addresses it stands out less as *our* address.
