Btrfs-progs: debug-tree, add option to dump a single tree

Very often while debugging filesystems with many subvolumes and/or
snapshots, specially when they are large, I want to see only the
content of one of the trees. So this change just adds an option
to btrfs-debug-tree to allow to specify the id of the tree we're
interesting in dumping to stdout.

Example:  btrfs-debug-tree -t 257 /dev/sdc

Will only dump the tree of the first snapshot or subvolume that was
created.
