btrfs-progs: Add -R to list UUIDs of original received subvolume
When using send/receive, it it useful to be able to match up source
subvols on the send side (as, say, for -p or -c clone sources) with their
corresponding copies on the receive side. This patch adds a -R option to
btrfs sub list to show the received subvolume UUID on the receive side,
allowing the user to perform that matching correctly.
