[PATCH 2/2] t2000: cleanup unused debug code and variables

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

From: Zakariyah Ali <zakariyahali100@gmail.com>

Remove the show_files function which is no longer used after removing
test_debug calls, and remove an unused tree3 variable assignment in
the second test scenario.

These cleanups address feedback from Junio C Hamano regarding the
modernization of this test script.
