@@@ tests: -e (errexit) shell option in scripts, where possible

Some test scripts run programs that return non-zero values for correct
outcome; those would fail the shell -e checks.

But some scripts not using -e are fine with it because we expect zero or
the error condition is handled otherwise. So, for robustness, the option is
added into them.
