Generate a spec file to be used with Artifactory in order to upload
files. By default, this will generate the file with the .deb, .tar*
and .gz files for uploading.
This will generate a spec file in the workspace called artifactory-spec-debian-pbuilder/debian-pbuilder.spec
which you can then use to upload the binaries to Artifactory. This is intended to be used
in conjunction with the Artifactory Jenkins plugin.
