bitbake: knotty: Allow displaying of status when no tasks are active 

The console can appear to hang when no tasks are executing even if bitbake
is iterating through a large number of tasks behind the scenes.

This patch tweaks the footer code to display a status even when no tasks
are active to give the user better feedback about what is happening.

(Bitbake rev: 0a950ee14fce3a0cb938c22d7c717dc93ce6e25f)
