[PATCH v2 2/2] kunit: tool: Mark 'kunittest_config' as constant again

[SeongJae Park <sjpark@amazon.com>]

From: SeongJae Park <sjpark@amazon.de>

'kunit_kernel.kunittest_config' was constant at first, and therefore it
used UPPER_SNAKE_CASE naming convention that usually means it is
constant in Python world.  But, commit e3212513a8f0 ("kunit: Create
default config in '--build_dir'") made it modifiable to fix a use case
of the tool and thus the naming also changed to lower_snake_case.
However, this resulted in a confusion.  As a result, some successing
changes made the tool unittest fail, and a fix[1] of it again incurred
the '--build_dir' use case failure.

As the previous commit fixed the '--build_dir' use case without
modifying the variable again, this commit marks the variable as constant
again with UPPER_SNAKE_CASE, to reduce future confusions.

[1] Commit d43c7fb05765 ("kunit: tool: fix improper treatment of file location")
