EvasionTrackingTests: both guns on the one shooter, at the origin at rest

Browse source 
A ship's targeting gear carries its own item quality, so Tracking(shooter) differs between two ships fitted alike:
the gun-times-ship comparison needs two designs on one ship. The gunner now carries FastBlast+- and ColdFire, and
the mount fixture puts it back at the origin so the sweep is the geometry the test states.
