Fix rtapp tasknames matching
Created by: derkling
Here is a small set of changes required to update rt-app to a more recent version.
We basically get back RTATestBundle
working which is broken since:
https://github.com/scheduler-tools/rt-app/pull/53
has been merged to forcing all generated rt-app task to have a -NUMER
suffix.
Since we are at that we update also rt-app with the current master, right after we drop support for ppc64le since there are not main users our there: @jlelli scream if you really need it ;)
