After tst_res(TFAIL | TTERRNO, ...) the result is already recorded by
the framework. The child's exit code is used only to detect crashes or
unexpected termination.

Once verify_execve() returns, the framework calls tst_reap_children(),
which invokes check_child_status(). That function does:

  if (WEXITSTATUS(status))
      tst_brk(TBROK, "Invalid child (%i) exit value %i", ...);

So exit(EXIT_FAILURE) will produce a spurious TBROK on top of the
already-reported TFAIL. The convention in LTP is to call exit(0) after
reporting a result through tst_res() in a child process.

Verdict: Needs revision
