[PATCH] t4200-rerere.sh: use test_path_is_* functions in the script

["Allo via GitGitGadget" <gitgitgadget@gmail.com>]

From: Angel Pan <dinoallosaurus1111@gmail.com>

This is a microproject for GSoC.
The original code works fine. However, since the code base has already have help-functions(in test-lib-functions),
the change is able to help people understand the code better, as well as improve debug-friendliness.

    [GSoC/PATCH] t4200-rerere.sh: use test_path_is_* functions in the script
    
    Hello again. I have sent a mail here: last mail
    [https://lore.kernel.org/git/CAFk=nY7efz8ZisEuyAcU09J+ja4qE8LorUUPeupGVEjBBc6HDA@mail.gmail.com/T/#u]
    After all, I decided to replace test -(e|f|d) with test_path_is_*
    functions as my microproject for GSoC. I am looking forward to working
    with every contributor here. I also have another question: For a commit
    like this involving 10+ insertions, would it be better if I
    seperate-commited all of them? But this kind of change seems trivial...
