CCv0: functional/sev: fix error cloning repositories

[wainersm]

If the sevctl and simple-kbs directories already exist on the workspace then the git clone will fail. Ensure the directory doesn't exist, and if it does then update the source tree.

This fix will be useful for when running the test locally. On CI side I provided another solution which is to wipe out the workspace before the build starts: https://github.com/kata-containers/ci/pull/493

@wainersm - I think this PR is out of date and the code has moved on, so can we close it, or should it be rebased and update where the sev tests are now?
