t9903: add tests for bash.showUntrackedFiles

Add 4 tests for the bash.showUntrackedFiles config option, covering
all combinations of the shell var being set/unset and the config
option being enabled/disabled (the other 2 cases, missing config
with and without shell variable, are already covered by existing
tests).
