Tie-File: report test timeouts to STDERR

Currently some tests have a 5 second timeout. If this is exceeded,
the test number is output as "not ok", along with "# Timeout" to
STDOUT. Change the latter to output to STDERR along with the test
filename and test number, for easer debugging of smoke logs.

(Really these test files need upgrading to use Test::* but that's a job
for another day and another person....)
