cgit.c: improve error message when git repo cannot be accessed

The current 'Not a git repository' error message is not very helpful,
since it doesn't state the cause of the problem.

This patch uses errno to provide a hint of the underlying problem. It
would have been even better to give the exact cause (e.g. for ENOENT it
would be nice to know which file/directory is missing), but that would
require reimplementing setup_git_directory_gently() which seems a bit
overkill.
