Subject: [PATCH] [Build] Fix nightly build TP and drop unused upstream trigger
 handling

Upstream builds that trigger the Xtext Jenkins pipelines do not exist
anymore and therefore isTriggeredByUpstream() always returns false.
With that assumption the pipline can be simplify and also
selectedTargetPlatform() can be removed.
The latter returned an erroneous tp file name fragment anyways if it
where called by an upstream job.
