mkdir(2) function returns EROFS error even when the path already exists on the
read only file system, so it is impossible to determine whether the path already
exists on this kind of fs only be return code from the mkdir(2). To make
cg_mkdir_p() compatible with the ro fs, the function checks whether the path
exists with stat(2) before trying to create it.
