[libvirt] [PATCH] util: Implement and use virFileIsRegular() rather than d_type
The dirent's d_type field is not portable to all platforms. So we have
to use stat() to determine the type of file for the functions that need
to be cross-platform. Fix virFileChownFiles() by calling the new
virFileIsRegular() function.
