Cleaned up test script and directory naming

- Removed old tests and test scripts
- Reorganize the block devices to live under one directory
- Plugged new test framework into Makefile

renamed:
- scripts/test_.py -> scripts/test.py
- tests_ -> tests
- {file,ram,test}bd/* -> bd/*

It took a surprising amount of effort to make the Makefile behave since
it turns out the "test_%" rule could override "tests/test_%.toml.test"
which is generated as part of test.py.
