btrfs-progs: Beautify owner when printing leaf/nodes 

Currently we print the raw values of the owner field of leaf/nodes.
This can result in output like the following:

leaf 30490624 items 2 free space 16061 generation 4 owner 18446744073709551607

With the patch applied the same leaf looks like:

leaf 30490624 items 2 free space 16061 generation 4 owner DATA_RELOC_TREE
