tests: move all test-cases into component subdirectories

There are around 300 regression tests, 250 being in tests/bugs. Running
partial set of tests/bugs is not easy because this is a flat directory
with almost all tests inside.

It would be valuable to make partial test/bugs easier, and allow the use
of mulitple build hosts for a single commit, each running a subset of
the tests for a quicker result.

Additional changes made:
- correct the include path for *.rc shell libraries and *.py utils
- make the testcases pass checkpatch
- arequal-checksum in afr/self-heal.t was never executed, now it is
- include.rc now complains loudly if it fails to find env.rc
