services: Specify serialVersionUID for the dummy SocketAddress

This fixes a serial warning that breaks the build when building
_without_ ErrorProne. I have no clue why _disabling_ ErrorProne makes
the warning pop up, but whatever, the warning is legit.

I also gave it a name, since the anonymous $1 seems weird if we're
providing a serialVersionUID. Not to say we're actually supporting
serializing this object. But if we ever see a serialized form show up in
the future, having a more clear name would make it obvious what it is.
