read_early_config(): really discover .git/

Earlier, we punted and simply assumed that we are in the top-level
directory of the project, and that there is no .git file but a .git/
directory so that we can read directly from .git/config.

However, that is not necessarily true. We may be in a subdirectory. Or
.git may be a gitfile. Or the environment variable GIT_DIR may be set.

To remedy this situation, we just refactored the way
setup_git_directory() discovers the .git/ directory, to make it
reusable, and more importantly, to leave all global variables and the
current working directory alone.

Let's discover the .git/ directory correctly in read_early_config() by
using that new function.

This fixes 4 known breakages in t7006.
