tests: Add testcase for ffi callbacks.

tests: Convert remaining "sys.exit()" to "raise SystemExit".

tests: Make ffi_callback.py be able to run on uclibc and macosx. Similar to ffi_float.py.

tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.
