JJB: package name does not match and breaks PBR

[Emilien Macchi]

Running JJB from master:

bash-4.2$ jenkins-jobs update --delete-old /etc/jenkins_jobs/jobs
Traceback (most recent call last):

    raise Exception("Versioning for this project requires either an sdist"
Exception: Versioning for this project requires either an sdist tarball, or access to an upstream git repository. Are you sure that git is installed?

This issue appears since this commit (which uses PBR):
https://github.com/openstack-infra/jenkins-job-builder/commit/b77a9991eed45a31dea7941ed0acf5935dc3869e

Because package name in setup.cfg is different from package_name discovered by PBR:
[metadata]
name = jenkins-job-builder

[files]
packages = jenkins_jobs

The traceback for this looks like bug 1379579 though Emilien mentioned in IRC that he observed this with setuptools 0.9.8 on RHEL 7.

    Get verison info for jenkins-job-builder

    Old setuptools/distribute VersionInfo() needs the dist name not the
    package name to get the correct version info. Switch to using
    'jenkins-job-builder' which is the dist name instead of using
    'jenkins_jobs' which is the package name so that we get the right data
    when processing versions on old setuptools.
