[PATCH v2 13/17] t5619: wrap `test_commit_bulk` in `GIT_DIR` subshell for bare repo

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

From: Johannes Schindelin <johannes.schindelin@gmx.de>

To prepare for `safe.bareRepository` defaulting to `explicit` (see
8d1a7448206e), wrap the `test_commit_bulk` call in `(GIT_DIR="$REPO" &&
export GIT_DIR && test_commit_bulk ...)` because `test_commit_bulk -C`
relies on implicit discovery which would fail once the default changes.
