kunit: kunit_tool: Fix invalid result when build fails

When separating out different phases of running tests[1]
(build/exec/parse/etc), the format of the KunitResult tuple changed
(adding an elapsed_time variable). This is not populated during a build
failure, causing kunit.py to crash.

This fixes [1] to probably populate the result variable, causing a
failing build to be reported properly.
