[JENKINS-21421] GIT_BRANCH_SHORT for branch name without release/, feature/, etc. Just the bit after the '/'

For cases where a filename expansion is needed for the git branch name, thre cannot be a '/' in a filename, so that part of the branch needs to be dropped.

ie:

GIT_BRANCH=release/blue-fish

then:

GIT_BRANCH_SHORT=blue-fish

Seems like a simple thing to do in the plugin, but not possible to do in a job.
