Filter out Assessment and Deployment Kit

When packaging the VC++ and Windows SDK toolchain it is important to
filter out unneeded directories both to avoid unnecessary size and to
avoid including excessively long paths. The Assessment and Deployment
Kit was installed on my test machine, is 3.5 GB, and has some very
long file paths, so now I filter it out.
