btrbk: fix filter statement matching for volume="/" 

While $vol->{URL} can contain "//" if volume="/" (intentionally, this
is an assembled path), the filter statements are sanitized using
check_url(). This means we need to match the filter statement against
check_url($vol->{URL}). Same applies to subvol.
