bitbake: knotty: import latest python-progressbar

Since we're going to make some minor extensions to it, it makes sense to
bring in the latest version of python-progressbar. Its structure has
changed a little but the API hasn't; however we do need to ensure our
overridden _needs_update() function's signature in BBProgress() matches
properly.

+"""Text progress bar library for Python.
+
+A text progress bar is typically used to display the progress of a long
+running operation, providing a visual cue that processing is underway.
+
+The ProgressBar class manages the current progress, and the format of the line
+is given by a number of widgets. A widget is an object that may display
+differently depending on the state of the progress bar. There are three types
+of widgets:
+ - a string, which always shows itself
+
+ - a ProgressBarWidget, which may return a different value every time its
+   update method is called
+
+ - a ProgressBarWidgetHFill, which is like ProgressBarWidget, except it
+   expands to fill the remaining width of the line.
+
+The progressbar module is very easy to use, yet very powerful. It will also
+automatically enable features like auto-resizing when the system supports it.
