Title:
  dpkg-source on xenial doesn't support .asc file in .dsc for v1.0
  source format

Status in dpkg package in Ubuntu:
  Fix Released
Status in dpkg source package in Xenial:
  Fix Committed

Bug description:
  [Impact]
  Source packages built on bionic where the upstream tarball comes with an upstream signature (.asc) are rejected by the ftpmaster, because dpkg-source there is too old.

  This is also affecting Debian imports in launchpad.

  [Test Case]
  Build a source pkg with a tarball & .asc on bionic, extract on xenial

  [Regression Potential]
  None.  The patch is very simple and merely recognizes the file as a valid member and then does nothing with it.
