bitbake/knotty: avoid printing full task log when error already printed

If a task has logged an ERROR then don't print the contents of the
task's log file in knotty (the default terminal UI).

As a side-effect we now also respect BBINCLUDELOGS in knotty; if it is
false we never print the log (but the pointer to the log file is always
printed).
