Draft: Also remove the access files in arc.conf.d

In TestCA for the new arc.conf.d files - the directory was missing in the filename, causing the files in /etc/arc.conf.d to remain. In TestJWT the implementation to remove the arc.conf.d files was missing altogether

I have added an additional cleanup command to just cleanup access, i.e. remove files in arc.conf.d only, arcctl test-jwt cleanup_accessandarcctl test-ca cleanup_access` while cleanup takes it all files as before.
