Introduce KUNIT_INDENT macro which corresponds to 4-space indentation,
and use it to modify indentation from tab to 4 spaces.

Sorry for the late comment.

This change looks good except for one thing: kunit_tool
(tools/testing/kunit/kunit.py) expects the wrong indentation. Can you
fix it? I think it would be best to fix it in this change so that
there is point at which it is broken.

Currently, this change breaks it. For example, with
CONFIG_KUNIT_TEST=y and CONFIG_KUNIT_EXAMPLE_TEST=y. kunit_tool
reports the following:

Testing complete. 0 tests run. 0 failed. 0 crashed.

I am pretty sure the change needs to happen in
tools/testing/kunit/kunit_parser.py.

Cheers
