bitbake: toaster: fix wrong usage of print_exc and format_exc

First parameter of traceback.print_exc and traceback.format_exc APIs is
a 'limit' - a number of stracktraces to print.

Passing exception object to print_exc or format_exc is incorrect, but
it works in Python 2 and causes printing only one line of traceback.

In Python 3 comparison of integer and exception object throws exception:
TypeError: unorderable types: int() < <Exception type>()

As these APIs are usually used in except block of handling another
exception this can cause hard to find and debug bugs.
