subs/control: Fix to ignore embarked land units

Moving stuff out of an occupied sector generally requires "military
control", i.e. you need at least one military for every ten civilians.
Military in land units count.  Even when the land unit is loaded on a
ship or land unit.  Questionable, because unload need not be possible.

Checking whether unload would be possible is not worth the trouble
here, simply ignore embarked land units.

This affects commands move, explore, sell, set and transport, as well
as the update's distribution and delivery.
