libblkid: don't interpret regual XFS as external xfs log

 $ blkid -o udev -p tests/output/blkid/images-fs/xfs.img
 ID_FS_AMBIVALENT=filesystem:xfs other:xfs_external_log

it seems that regular XFS with internal log may be interpreted as log
device. This is incorrect.

This patch checks for XFS magic string to avoid this collision.
