fix(tools): Fix packaging libs and zips on linux. (#6327)

Both OSX and Linux builds were not excluding two libs from their zip
file due to a missing comma. You can see that they both exist within the
live client manifests.

Also fix the MS dlls having basically no date set on the file which is
throwing an error when trying to zip them.
