t5613: drop reachable_via function

This function was never used since its inception in dd05ea1
(test case for transitive info/alternates, 2006-05-07).
Which is just as well, since it mutates the repo state in a
way that would invalidate further tests, without cleaning up
after itself. Let's get rid of it so that nobody is tempted
to use it.
