[PATCH 2/2] checkpatch: Fix detection of git repository

[Richard Genoud]

Since git v1.7.7, the .git directory can be a file when, for example,
the kernel is a submodule of another git super project.
So, the check "-d .git" is not working anymore in this case.
Using a more generic check like "-e .git" corrects this behaviour.
