6ec1b81d35 kunit: Fix '--build_dir' option
Running kunit with '--build_dir' option gives following error message:

```

```

This error occurs because the '--build_dir' option value is not passed
to the 'run_kernel()' function.  Consequently, the function assumes
the kernel image that built for the tests, which is under the
'--build_dir' directory, is in kernel source directory and finally raises
the 'FileNotFoundError'.

This commit fixes the problem by properly passing the '--build_dir'
option value to the 'run_kernel()'.

ff7b437f36 kunit: defconfig: add defconfigs for building KUnit tests
Add defconfig for UML and a fragment that can be used to configure other
architectures for building KUnit tests. Add option to kunit_tool to use
a defconfig to create the kunitconfig.

6ebf5866f2 kunit: tool: add Python wrappers for running KUnit tests
The ultimate goal is to create minimal isolated test binaries; in the
meantime we are using UML to provide the infrastructure to run tests, so
define an abstract way to configure and run tests that allow us to
change the context in which tests are built without affecting the user.
This also makes pretty and dynamic error reporting, and a lot of other
nice features easier.

kunit_config.py:
  - parse .config and Kconfig files.

kunit_kernel.py: provides helper functions to:
  - configure the kernel using kunitconfig.
  - build the kernel with the appropriate configuration.
  - provide function to invoke the kernel and stream the output back.

kunit_parser.py: parses raw logs returned out by kunit_kernel and
displays them in a user friendly way.

test_data/*: samples of test data for testing kunit.py, kunit_config.py,
etc.
