[test] Move MY_RELAY to p2p.py

messages.py is for message and primitive data structures. Specifics
about the test framework's p2p implementation should be in p2p.py.

Also rename to P2P_VERSION_RELAY. Also rename msg_version.nRelay to
relay. In Bitcoin Core, this is referred to as fRelay, since it's a
bool, so this field has always been misnamed.
