tests: use "test_stdout_line_count", not "test $(git [...] | wc -l)"

Use the test_stdout_line_count helper added in
cdff1bb (test-lib-functions: introduce test_stdout_line_count,
2021-07-04) so that we'll spot if git itself dies, segfaults etc in
these expressions.

Because we didn't distinguish these failure conditions before I'd
mistakenly marked these tests as passing under SANITIZE=leak in
dd9cede (leak tests: mark some rev-list tests as passing with
SANITIZE=leak, 2021-10-31).

While we're at it let's re-indent these lines to match our usual
style, as we're having to change all of them anyway.
