[PATCHv2] sstate.bbclass: Always show a progress bar if an sstate summary is wanted

[Peter Kjellerstedt <pkj@axis.com>]

In case sstate_checkhashes() is expected to show an sstate summary, then
always show the "Checking sstate mirror object availability" progress
bar regardless of how long the task list is. Without this, the sstate
summary could unintentionally overwrite the "Initialising tasks"
progress bar, which may still be active. Forcing the "Checking sstate
mirror object availability" progress bar to show will make sure the
"Initialising tasks" progress bar is finalized before the sstate summary
is shown, and the output of the progress bars and the sstate summary
will be as expected.

PATCHv2: Make sure the case when the tasklist is empty is also handled
         correctly.
