Subject: [PATCH] kunit: run kunit_tool from any directory

Implemented small fix so that the script changes work directories to the
linux directory where kunit.py is run. This enables the user to run
kunit from any working directory. Originally considered using
os.path.join but this is more error prone as we would have to find all
file path usages and modify them accordingly. Using os.chdir ensures
that the entire script is run within /linux.
