Select test data directory using generated list

Remove a hardcoded list of tests that use generated
".data" files, and instead derive this list from the existing
list of test files (created using generate_psa_tests.py).

This reduces the maintenance burden as only the list
in generate_psa_tests.py needs to be updated.
