libmakepkg: Use git -c safe.bareRepository=all in bare repositories

Browse source 
Git commands can fail in bare repositories when global git config contains safe.bareRepository=explicit.
Some users set this option for increased security.
To be compatible with this configuration, explicitly set safe.bareRepository=all when invoking git in a bare repository.
