oeqa: selftest: context: run tests serially if testtools/subunit modules are not found

Browse Source 
If testtools and/or subunit modules are not found we get the following backtrace
(example for testtools):

  NOTE: Starting bitbake server...

      import testtools
  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
