[OE-core] [PATCH] python3-testtools: Avoid traceback2 module requirement

[Richard Purdie]

traceback2 adds traceback for python2. Rather than depend on traceback2, we're
python3 only so just use traceback.

This caused breakage in oe-selftest -j which uses testtools on the autobuilder
using buildtools-tarball.
