Having these named differently than the test itself mostly creates unecessary confusion and makes writing logic against the tests harder so let's rename the testsuite-xx units and scripts to just use the test name itself.
aCdDefLprRwxXz are tested with --dry-run. I added a primitive test of bc. There were no tests for AhHt, and I didn't add those either.
So we can extend it with additional utility functions without making it confusing. No functional change.
