test-archive: silence stupid messages from GNU tar

Recent versions of GNU tar have apparently decided they're old enough
that it's ok for them to prattle on senselessly about things no one
cares about without anyone objecting. We object; apply duct tape.

#!/usr/bin/env python

try:
    fp = file(os.environ['DAEMON_PIDS'])
    for line in fp:
        try:
            pid = int(line)
        except ValueError:
            continue
        try:
            os.kill(pid, 0)
            os.kill(pid, signal.SIGTERM)
            for i in range(10):
                time.sleep(0.05)
                os.kill(pid, 0)
            os.kill(pid, signal.SIGKILL)

                raise
    fp.close()
except IOError:
