Don't run EE specific tests for CE images
For triggered jobs, we need not run EE specific tests if the image is a CE one. Hence we check if the RELEASE variable (which is used only in triggers) matches gitlab-ce and exits the build if that is the case.
Until something like https://gitlab.com/gitlab-org/gitlab-ce/issues/37397 is implemented
