Subject: [PATCH AUTOSEL 5.8 64/72] kunit: tool: fix improper treatment of file location

From: Brendan Higgins <brendanhiggins@...gle.com>

[ Upstream commit d43c7fb05765152d4d4a39a8ef957c4ea14d8847 ]

Commit 01397e822af4 ("kunit: Fix TabError, remove defconfig code and
handle when there is no kunitconfig") and commit 45ba7a893ad8 ("kunit:
kunit_tool: Separate out config/build/exec/parse") introduced two
closely related issues which built off of each other: they excessively
created the build directory when not present and modified a constant
(constants in Python only exist by convention).

Together these issues broken a number of unit tests for KUnit tool, so
fix them.

Fixed up commit log to fic checkpatch commit description style error.
