hgweb: build the "entries" list directly in filelog command

There's no apparent reason to have this "entries" generator function that
builds a list and then yields its elements in reverse order and which is only
called to build the "entries" list. So just build the list directly, in
reverse order.

Adjust "parity" generator's offset to keep rendering the same.
