m/pkg/logtree/unraw: deflake tests

This test was flaking quite seriously on CI, due to races between the
supervisor's test harness logging a startup message and the test's own
logging exercise logic.

Fixing that, I also spotted a rare flake that occurs when a
NamedPipeReader restart races a write to the named pipe, possible
causing the write to be sent to the old but still running
NamedPipeReader. We fix that in the test, as fixing this in the code
itself is difficult and the resulting problem (a lost log line in this
rare race condition) isn't that bad.
