oeqa/utils/__init__.py: Adds compatibility with bitbake logger

The bitbake logger changes the way debug is logged and adds
different levels within debug, this is passed as argument
to the function and breaks compatibility with vanilla loggers.

This implements a way to handle this adding a new function for
debug, that will dispatch the correct logging method signature.

Also overrides info method to use logging.INFO + 1 in order to
see plain data.

Also this commit fix the issue of not showing the test summary
and results when running from bitbake.
