test_CVE_2012_2944 autopkgtest is racy

[Martin Pitt]

As you can see in the build history of https://jenkins.qa.ubuntu.com/job/trusty-adt-nut/? the test_CVE_2012_2944 test is rather flaky:

======================================================================
FAIL: test_CVE_2012_2944 (__main__.BasicTest)
Test CVE-2012-2944
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/tmp/adt-run.akeFyu/dsc0-build/nut-2.7.1/debian/tests/test-nut.py", line 396, in test_CVE_2012_2944
    self.assertFalse(os.path.exists(pidfile), "Found %s" % pidfile)
AssertionError: Found /var/run/nut/upsd.pid

I often have to retry the package test two or three times before it succeeds, particularly when the test machines are busy. So either the test isn't right, or the security issue that it's supposed to fix isn't really fixed?

*sigh*, this test is impossible to satisfy, I now got ~ 15 failures in a row and this is holding up other packages. This has been ignored for 4 months, taking bug now.

This bug was fixed in the package nut - 2.7.1-1ubuntu3

---------------
nut (2.7.1-1ubuntu3) utopic; urgency=medium

  * debian/tests/test-nut.py: in the CVE_2012_2944 test, give nut at most 5
    seconds to shut down, instead of expecting it to be shut down immediately
    after sending the killall. (LP: #1291378)
