git-gui: Fixes chooser not accepting gitfiles

Browse Source 
Support the case where .git is a platform independent symbolic link
and not a directory. This occurs when --separate-git-dir is used when
creating the local repository to store the .git directory elsewhere.

git-gui does not support such repositories when using the repository
chooser as the test to determine that the chosen directory is a git
repository fails for such repositories.

This commit enables _is_git to read the real location from the
symbolic link file.
