Fix airlifting over huge distances legality.

Airlifting from any city to any city should be allowed according to the old
rules. When "Airlift Unit" became action enabler controlled it got
MAP_MAX_LINEAR_SIZE as its maximum distance. It was assumed to cover the
whole map. The assumption was wrong. A map can be non wrapping. It can also
forbid some diagonal movement.

See bug #24997
