search_dir() recurses down the btrfs tree, and used to take the output
path for every item (i.e. in the running system, output root directory
concatenated with btrfs-local pathname) passed as the only path
parameter. Moving the output root directory to a separate parameter
and passing the btrfs-local pathname for each file and directory
separately allows easy filtering based on the btrfs-local pathname.
