kunit: tool: simplify code since build_dir can't be None

Browse Source 
--build_dir is set to a default of '.kunit' since commit ddbd60c779
("kunit: use --build_dir=.kunit as default"), but even before then it
was explicitly set to ''.

So outside of one unit test, there was no way for the build_dir to be
ever be None, and we can simplify code by fixing the unit test and
enforcing that via updated type annotations.

E.g. this lets us drop `get_file_path()` since it's now exactly
equivalent to os.path.join().

Note: there's some `if build_dir` checks that also fail if build_dir is
explicitly set to '' that just guard against passing "O=" to make.
But running `make O=` works just fine, so drop these checks.
