Fix T81922: Pose bones F-Curves hidden for unselected objects

Whilst in pose-mode, the selection filter only includes other objects in
pose-mode instead of the object selection.

This makes sense as the selection of the pose bones what the user as
acting on in the 3D view.
The object selection only makes sense to use in object mode.
