Fix 8859381: Display of requires/produces in Build Industry window

Change the window to use a dynamically generated string of cargoes,
instead of one of a few fixed-length lists. With up to 16 cargoes
on each list, having 16 with the only difference how many are listed
seems like a bad maintenance idea.
