addrmgr: store address' supported service bits
In this commit, we update the serialized version of the AddressManager
to also store each address' service bits. This allows an address'
service bits to be properly set when read from disk, which allows
external callers to reliably filter out addresses which do not support
their required services.

Since the service bits were not previously stored, the serialization
version needed to be bumped. A test has been added to test the behavior
of upgrading from version 1 to 2.
