Revert "build-and-provide-package: use -b for package builds that shouldn't include sources" [Closes: #88]

This reverts commit 649c70812e9ff22a0bb55f4719dff31d0c2e1e72.

The "-b" approach was just wrong when trying to fix:

| dh_virtualenv: error: no such option: -a

since any dh script should accept -a and -i.
Will follow up with a bug report against dh-virtualenv to
address the issue there.

Thanks: Christoph Berg <christoph.berg@credativ.de> for feedback
Release new version 0.8.1
Pass DIST and ARCH to cowbuilder call

Pass DIST and ARCH to cowbuilder call, so that is actually available to
it. This way its actually possiible to use the information in pbuilder
hooks, e.g. for the inclusion of (dist- or arch-specific) extra repos
Empty 'distribution' and 'architecture' env vars now do not break script when calling cowbuilder.

Note that sudoers may need to allow DIST and ARCH environment
variables to be passed, e.g.

Defaults  env_keep+="DIST ARCH"
puppet: allow DIST + ARCH in sudo configuration

Required for change in git commit 08248d68
No need to source /etc/jenkins/debian-glue twice in the same script
generate-git-snapshot: Support PRE_DCH_HOOK variable for custom scripts

This allows stuff like:

  echo "sed -i 's/^Section: _SECTION_/Section: dev/' debian/control" > /tmp/changeVersion.sh
  export PRE_DCH_HOOK="/tmp/changeVersion.sh"
  /usr/bin/generate-git-snapshot

Thanks: Rudolph Bott <bott@sipgate.de> for the patch
