add -i tests: mark "TODO" depending on GIT_TEST_ADD_I_USE_BUILTIN

Fix an issue that existed before 0527ccb1b55 (add -i: default to the
built-in implementation, 2021-11-30), but which became the default
with that change, we should not be marking tests that are known to
pass as "TODO" tests.

When GIT_TEST_ADD_I_USE_BUILTIN=1 was made the default we started
passing the tests added in 0f0fba2cc87 (t3701: add a test for advanced
split-hunk editing, 2019-12-06) and 1bf01040f0c (add -p: demonstrate
failure when running 'edit' after a split, 2015-04-16).

Thus we've been emitting this sort of output:

	$ prove ./t3701-add-interactive.sh
	./t3701-add-interactive.sh .. ok
	All tests successful.

	Test Summary Report
	-------------------
	./t3701-add-interactive.sh (Wstat: 0 Tests: 70 Failed: 0)
	  TODO passed:   45, 47
	Files=1, Tests=70,  2 wallclock secs ( 0.03 usr  0.00 sys +  0.86 cusr  0.33 csys =  1.22 CPU)
	Result: PASS

Which isn't just cosmetic, but due to issues with
test_expect_failure (see [1]) we could e.g. be hiding something as bad
as a segfault in the new implementation. It makes sense catch that,
especially before we put out a release with the built-in "add -i", so
let's generalize the check we were already doing in 0527ccb1b55 with a
new "ADD_I_USE_BUILTIN" prerequisite.
