bitbake: knotty: Remove extra whitespace after task progress bars

For some reason, BBProgress.setextra() always adds a space at the end.
This prevents the task progress bars from filling the entire width of
the terminal, making them stop one character short. This looks odd
when shown together with the main progress bar, which does fill the
entire terminal width.
