[PATCH v2 04/17] t0056: allow implicit bare repo discovery for `-C` work-tree tests

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

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

The `git -C c/a.git --work-tree=../a` invocations in t0056-git-C.sh
enter what is technically the `.git` directory of a repository to
test `-C` combined with `--work-tree`. In doing so, the code relies on
implicit discovery of bare repositories, which 8d1a7448206e (setup.c:
create `safe.bareRepository`, 2022-07-14) prepared to be prevented by
default.

These tests verify the interaction between those flags, so changing them
to use `--git-dir` would defeat their purpose. So let's just temporarily
force-enable implicit discovery of bare repositories, no matter what
`safe.bareRepository` defaults to.
