Remove FTK tests and fix the local running for release 21.3

The FTK tests were still in the sample, this change removed them from the building. Also the selection of the data to run on if running the test scripts locally depended on some xml decoding wich no longer works in release 21.3, so these changes extract

NB: the files in the test directory, namely test/test_*.sh, are all autogenerated from the file utils/template.sh. It is this template.sh file that has changed so please DO NOT REVIEW any of the files in the test directory.

This package is not used in standard athena - it is only used for the ID Trigger ART tests.
