PATCH 1/1 knotty: Improve exception error message

Instead of:
"""
can only concatenate tuple (not "int") to tuple
"""
we now see:

"""
Traceback (most recent call last):
File "/media/build1/poky/bitbake/lib/bb/ui/knotty.py", line 324, in main
termfilter.updateFooter()
File "/media/build1/poky/bitbake/lib/bb/ui/knotty.py", line 210, in updateFooter

    lines = 1 + int(len(content) / (self.columns + 1))

TypeError: can only concatenate tuple (not "int") to tuple """

which makes tacking down and fixing the problem much easier.

Also ensure we set an error exit code.
