If testtools and/or subunit modules are not found we get the following backtrace
(example for testtools):
NOTE: Starting bitbake server...
Traceback (most recent call last):

ModuleNotFoundError: No module named 'testtools'
Fix this by adding a custom callback on -j/--num-processes parameter to
check testtools and subunit modules. Fallback to serial testing if
missing. This strategy is already used in sdk/context.py

If someone has a better suggestion instead of using print here, I'll
update the patch :)
