Fix unstable packaging-build-rpm jobs

The post-job logic for packaging-build-rpm jobs is failing on an error related to lftools versions, resulting in the jobs being marked unstable and the logs not being deployed to the logserver correctly.

Failing job example (doesn't deploy logs to logserver, so can't link to those):

https://jenkins.opendaylight.org/releng/view/packaging/job/packaging-build-rpm-fluorine/164/console

Fails with:

22:53:37 ---> create-netrc.sh

22:53:41 No matching distribution found for lftools[openstack]~=0.18.0 (from -r /tmp/requirements-mcKb.txt (line 1))

This patch tests adding the lf-infra-pre-build builder macro to the packaging-build-rpm-<stream> jobs.

It does fix the issue.
