dpkg-source does not create .pc without quilt

Trying to sync alien-arena we stumbled over this error:

This issue got fixed in dpkg 1.15.5.6[1] which got already merged into Lucid but the fix needs to be backported to the sync hosts.

[1]:
 dpkg (1.15.5.6) unstable; urgency=low

   * dpkg-source: with format "3.0 (quilt)" ensure quilt's .pc directory is
     created before trying to register a new patch in .pc/applied-patches.
     Thanks to Tommi Vainikainen <email address hidden> for the report and the
     patch. Closes: #561237
   * Fix dpkg-buildpackage to set "parallel=" in DEB_BUILD_OPTIONS instead of
     the invalid "parallel=-1" when option "-j" is given. Closes: #562038
   * Clarify how dpkg-source --print-format works and display messages on
     STDERR when the requested format is discarded. Closes: #560391
   * Add ${misc:Depends} in all Depends fields.
