Derive the DNS timeout assertion from the spec, and join the mock workers

The self-test's ceiling came from the mock's sleep (MOCK_SLOW_MS - 500), not
from opt->timeout: a resolve using a hardcoded 2400ms deadline that ignored
opt->timeout entirely still passed it. Derive the bound from opt->timeout so
the assertion tests the contract instead of the fixture.

The scaffolding also raced its own abandoned workers. mock_host.calls was read
while a worker was still writing it, and tearing the backend down at the end
raced the worker's freeaddrinfo read, ordered only by a sleep. Serialize the
counters under a mutex, wait for the backend calls to actually return instead
of guessing, and leave the backend installed, since an abandoned worker still
reads it. Drops the drain sleep: 6.0s -> 4.0s.

Also: --timeout now bounds resolution, so say so in the help text (the man page
is generated from it), and factor the three address-copy loops into a helper.
