Subject: [PATCH] kunit: Fix kunit.py parse subcommand (use null build_dir)

When JSON support was added in [1], the KunitParseRequest tuple was
updated to contain a 'build_dir' field, but kunit.py parse doesn't
accept --build_dir as an option. The code nevertheless tried to access
it, resulting in this error:

AttributeError: 'Namespace' object has no attribute 'build_dir'

Given that the parser only uses the build_dir variable to set the
'build_environment' json field, we set it to None (which gives the JSON
'null') for now. Ultimately, we probably do want to be able to set this,
but since it's new functionality which (for the parse subcommand) never
worked, this is the quickest way of getting it back up and running.

Fixes: 21a6d1780d5bbfca0ce9b8104ca6233502fcbf86 ("kunit: tool: allow generating test results in JSON")

This is a quick fix because kunit.py parse is completely broken: it
appears it was introduced in the rebase of the JSON parser after the
separation of concerns patch.
