[PATCH] t6030: add test for git bisect skip started with --term* arguments

[Bagas Sanjaya]

Trygve Aaberge reported [1] git bisect breakage when the bisection
is started with --term* arguments (--term-new and --term-old). In that
case, skipping with `git bisect skip` should cause HEAD to be changed,
but actually the HEAD stayed same after skipping.

Let's add the test to catch the breakage. Because there isn't any fixes
yet, mark the test as test_expect_failure.

Junio suggested that I should had written this test in t6030, not in
separate script as per [2], so that I could reuse the history from
existing tests.
