[PATCH] t4126: fix "funny directory name" test on Windows (again)

[Junio C Hamano <gitster@xxxxxxxxx>]

Even though "git update-index --cacheinfo" ought to be filesystem
agnostic, somehow

    $ git update-index --add --cacheinfo "100644,$empty_blob,funny /empty"

fails only there.  That unfortunately makes the approach of the
previous step unworkable.

Resurrect the earlier approach to protect the test with a
prerequisite to make sure we do not needlessly fail the CI.
