  dist upgrade crash tracebacks include a tmpdir name

Bug description:
  N.B. Before testing this bug ensure that python-apport is installed on
  Saucy.  See bug 1289604 for details.

  Test Case:
  1) run do-release-upgrade -d
  2) cancel the upgrade
  3) cd to /tmp/ubuntu-release-upgrader-XYZ/
  4) edit DistUpgrade/DistUpgradeController.py and put a division by zero error in the function askDistUpgrade (this is to make the release upgrader crash)
  5) sudo ./trusty --frontend=DistUpgradeViewGtk3
  6) Observe a system crash dialog and choose to report it
  7) Choose to view details of the crash report
  8) Observe a traceback with /tmp/ubuntu-release-upgrader-XYZ/ in it
  9) Do not submit the crash report

  With the packae from proprosed you'll see a DuplicateSignature field
  with XYZ replaced with tmpdir so /tmp/ubuntu-release-upgrader-tmpdir/

  
  Tracebacks from crashes in the release upgrader include a temporary directory name like so:

  Traceback (most recent call last):
    File "/tmp/ubuntu-release-upgrader-5gz_r8/trusty", line 10, in <module>
      sys.exit(main())
    File "/tmp/ubuntu-release-upgrader-5gz_r8/DistUpgrade/DistUpgradeMain.py", line 243, in main
      if app.run():

  Because the temporary directory name changes between systems and
  upgrade attempts duplicates are not often consolidated in the error
  tracker or in Launchpad.  Subsequently, it is difficult to judge the
  number of people affected by any particular crash in the release
  upgrade process.

  This should be fixed in the apport package hook for update-manager in
  Precise and ubuntu-release-upgrader in Saucy.
