Remove squadrons from Nevatim in Exercise Bright Star (#3345)

This is a (potentially) temporary modification for Exercise Bright Star
that moves one of its squadrons to Hatzerim and disables the other two.
The reason is because Nevatim is currently bugged and only 11 out of its
120 airfield parking spots are usable. You can place aircraft into the
other parking spots in the mission editor but they will all explode upon
entering the mission.
