* Fixed pets derived from immobile monsters not being able to walk (bugreport:3377, since r13789).

- This also fixes pets using original monster walk speed, instead of the one defined in pet db.
- Fixed pets not being able to attack (pet_attack_support and pet_damage_support) when derived from a monster, which is not able to attack.
