Do we really need the tst_exec.sh?

Doesn't it work if we add what is in the tst_exec here?

The whole point of [ -z "$LTP_IPC_PATH" ]; is to detect when we are
being re-executed by the tst_run_shell, so the else branch (which
isn't really needed, because we do exit in the if) was when the test did
run.

If you change the tests to be in functions and source the tst_loader.sh
at the end it should just work.
