Fix T47773: Particle System with Boids Crash.

Problem was, during initialization of boids particles in `dynamics_step()`,
psys of target objects was not obtained with generic `psys_get_target_system()`
as later in code, which could lead to some uninitialized `psys->tree` usage...

Think it's safe enough for 2.77, though not a regression.
