roller: Add "Roll-Count:" footer
If there are multiple rolls but none of them add footers, the
auto_roller recipe module tacks the footers it creates onto the end of
the body with no blank lines. Example: http://pwrev.dev/241953. In this
case, add a "Roll-Count:" footer just to keep the auto_roller footers
separate from the body of the roll.
