Apply camera smoothing to 'air stepheight' (#10025)

Browse Source 
Recent changes to collision code have changed the behaviour of the 'touching_ground'
bool in movement code. This had the effect of disabling camera smoothing when
'air stepheight' occurred when jumping onto a node while pressing forwards against
the node, causing an unpleasant sharp camera movement.

Rewrite the conditions for camera smoothing such that it is applied when jumping.
