libblkid: don't return error on empty files
Currently, the library does not allow to initialize blkid_probe if the
file (or block device) is empty. The empty file is reported as an
error. That's wrong. The empty file should be interpreted as a file
without any FS or PT. It means that
blkid_do_{probe,safeprobe,fullprobe}()
have to return 1 ("nothing").
