[PATCH v2 06/17] t1900: avoid using `-C <dir>` for a bare repository

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

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

To prepare for `safe.bareRepository` defaulting to `explicit` (see
8d1a7448206e), add an optional 6th parameter `repo_flag` (defaulting
to `-C`) to the `test_repo_info` helper, and use it in the caller that
wants to operate on a bare repository.
