tiles: remove old isIndustrialZone() function

Browse source 
Note: this old Industrial Zone checking function would erroneously
include the Coal power plant animated smoke.

You could see this bug by selecting "industrial zones" for the
overlay map, and looking closely where your coal power plants are.
You will see that the coal power plant is invisible in the overlay
except for the four tiles containing the smoke.
