pbuilder-dist: assume action is "build" if only a .dsc file is passed as argument

Implemented in my branch, marking this as fix committed as it should be in Hardy soon.

ubuntu-dev-tools (0.23) hardy; urgency=low

  [ Daniel Holbach ]
  * debian/control: bumped python-launchpad-bugs requirement to newest version
    and made it a Recommends. All scripts in ubuntu-dev-tools using it fail
    gracefully if it's not installed.
  * hugdaylist:
    - make use of text connector.
    - commentary in wiki output.

    removed a runon in DESCRIPTION.

  [ Siegfried-Angel Gevatter Pujals (RainCT) ]

       the next argument ends with .dsc (LP: #172940).
  * dgetlp:

  * 404main:
