for kldstat(2). This allows libdtrace to determine the exact file from which a kernel module was loaded without having to guess. The kldstat(2) API is versioned with the size of the kld_file_stat structure, so this change creates version 2. Add the pathname to the verbose output of kldstat(8) too. MFC: 3 days
