[PATCH 14/17] t6020: use `-C` for worktree, `--git-dir` for 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), adjust a loop that iterated over both a
bare (`cloned`) and a non-bare (`unbundled`) repository using
the same `-C` flag: the bare repo needs `--git-dir` to avoid
implicit discovery, while the non-bare one keeps `-C`.
