git-gui: Move feature option selection before GIT_DIR init

By moving our feature option determination up before we look for GIT_DIR
we can make a decision about whether or not we need a working tree up
front, before we look for GIT_DIR.  A future change could then allow
us to start in a bare Git repository if we only need access to the ODB.
