Implemented small fix so that the script changes work directories to the
root of the linux kernel source tree from which 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.

Thanks for  the patch. In the future please include changes from v1
to v2.

I am assuming this v2 addresses Frank's comments.
