chirp: add a 10s timeout when communicating with BIRD (#5444)
Prior to this change, if BIRD stops responding wgengine.watchdogEngine
will crash tailscaled.

This happens because in wgengine.userspaceEngine, we end up blocking
forever trying to write a request to or read a response from BIRD with
wgLock held, and then future watchdog'd calls will block on acquiring
that mutex until the watchdog kills the process. With the timeout, we at
least get the chance to print an error message and decide whether we
want to crash or not.

Updates tailscale/coral#72
