Chad Monroe 6e20811dfe unetmsg: fix TCP_USER_TIMEOUT socket option level ...

The ucode socket module exports no SOL_TCP so setopt() was called
with level 0 and silently failed. This left inter-node connections
without the 5 second user timeout. A peer that stopped reading
could then stall a blocking channel write forever, deadlocking
every unetmsgd in the mesh along with their local clients.

Use IPPROTO_TCP and warn when setopt fails.
