Make setup_git_env() resolve .git file when $GIT_DIR is not specified
This makes reinitializing on a .git file repository work.
This is probably the only case that setup_git_env() (via
set_git_dir()) is called on a .git file. Other cases in
setup_git_dir_gently() and enter_repo() both cover .git file case
explicitly because they need to verify the target repo is valid.
