util/testing: Allow jenkins builders to skip testing areas

With the addition of the clang tests, the jenkins builds are taking a
really long time to run the tests.  This change allows the
"what-jenkins-does" build to be split into separate builds on jenkins.

Additionally, some jenkins builds like coverity don't need (or want)
to build clang or even the linters.

Update help with the variables.
