Include x.yyy.z-lts tags in labeling (#1165)

Fix jenkins-infra/release#176

The 2.289.3 Docker image creation did not generate tags for:

* jenkins/jenkins:2.289.3-lts
* jenkins/jenkins:2.289.3-lts-alpine
* jenkins/jenkins:2.289.3-lts-centos
* jenkins/jenkins:2.289.3-lts-centos7
* jenkins/jenkins:2.289.3-lts-jdk11

This restores that behavior, though it may be temporary, since we're
making other changes for the 2.302.1 release.
