t/zbd: add -t option to run-tests-against-nullb

For debugging, it can be useful to run a single ZBD test case in all
zoned configurations defined in run-tests-against-nullb. Add -t option
to run-tests-against-nullb so that the single ZBD test case specified
in run-tests-against-nullb command line is executed in all sections
of the script.
