[Buildroot] [PATCH 1/2] support/run-tests: move packages tests to packages directories

[Yann E. MORIN]

Move the existing few packages' tests to the correspnding package
directories.

If we were to add the package/ directory to nose2's search path, we
would have to add __init__.py files about everywhere, at each level of
the directory hierarchy, because nose2 only includes tests that are in a
python pacakge (a directory with a __init__.py file is a python package).
This is far from ideal, especially since we have absolutely nothing to
put in those __init__.py files.

An alternative is to just scan the package/ directory ourselves, and
create symlinks in a sub-directory of support/tessting/tests/ so that
nose2 does find them. We have no two packages with the same name, we
don't risk having two symlinks with the same name.

That second solution is what we choose to do, at the cost of a slight
increase in complexity in the run-test script.
