Make the findsuper program more powerful

Improve the findsuper program by printing the uuid and label from the
superblocks, as well as the starting and ending offsets of the
filesystem given the information in the superblock.  Omit by
default printing superblocks that are likely found in located in an ext3
journal unless an explicit -j option is given.
