  apport_excepthook called with incorrect number of arguments

Bug description:
  When there was a failure to handle an upgrade, apport_crash() gets
  called to handle it and it calls apport_excepthook(), but it is
  missing an argument in that call:

  Error in sys.excepthook:
  Traceback (most recent call last):
    File "/tmp/ubuntu-release-upgrader-rj__cqhy/DistUpgrade/DistUpgradeViewText.py", line 138, in _handleException
      apport_crash(type, value, tb)
    File "/tmp/ubuntu-release-upgrader-rj__cqhy/DistUpgrade/DistUpgradeApport.py", line 57, in apport_crash
      apport_excepthook(type, value, tb)
  TypeError: apport_excepthook() missing 1 required positional argument: 'exc_tb'

  In my case, that was because I had Apt::Default-Release "noble"; in my
  apt.conf. That issue is on me and I've fixed that misconfiguration.
  However, this bug is about the second exception that was triggered
  when trying to handle the first exception. It seems that
  apport_excepthook is missing the binary argument. Maybe apport_crash()
  needs to be passing in sys.argv[0] in DistUpgradeApport.py on it's
  call to apport_excepthook()??

  This crash can also be seen in another, recent bug report:
