bisect tests: test for v2.30.0 "bisect run" regressions

Add three failing tests which succeed on v2.29.0, but due to the topic
merged at [1] (specifically [2]) have been failing since then. We'll
address those regressions in subsequent commits.

There was also a "regression" where:

	git bisect run ./missing-script.sh

Would count a non-existing script as "good", as the shell would exit
with 127. That edge case is a bit too insane to preserve, so let's not
add it to these regression tests.

There was another regression that 'git bisect' consumed some options
that was meant to passed down to program run with 'git bisect run'.
Since that regression is breaking user's expectation, it has been fixed
earlier without this patch queued.
