setup: allow cwd=.git w/ bareRepository=explicit
The safe.bareRepository setting can be set to 'explicit' to disallow
implicit uses of bare repositories, preventing an attack [1] where an
artificial and malicious bare repository is embedded in another git
repository. Unfortunately, some tooling uses myrepo/.git/ as the cwd
when executing commands, and this is blocked when
safe.bareRepository=explicit. Blocking is unnecessary, as git already
prevents nested .git directories.
Teach git to not reject uses of git inside of the .git directory: check
if cwd is .git (or a subdirectory of it) and allow it even if
safe.bareRepository=explicit.
