Robin Stocker 2d9c72ffb1 cli/tests: Prevent git.subprocess from reading outside git config
A subset of cli tests could fail if the system /etc/gitconfig had
configuration interfering with the tests. The cause seems to be running
of `jj` commands that would in turn use a `git` subprocess.

Fix this by setting `GIT_CONFIG_SYSTEM` and `GIT_CONFIG_GLOBAL`, like
in `hermetic_git`.

Fixes #6159
