btrfs: add "rescue=usebackuproot" into "rescue=all" shortcut

Browse Source 
The mount option "rescue=all" should be a shortcut to include all
"rescue=" mount options. But unfortunately "rescue=usebackuproot" is not
included.

Include that option so "rescue=all" has a better chance to mount a
corrupted fs.
