Hack to put packages in the autotest dir as well as autotest/packages.

Since we are using old and new code we are running in to issues where files
are expected to be in two different places. This adds a temporary fix that
copies the package files up one level in <build>/autotest from
<build>/autotest/packages.

TEST=Ran staging locally and confirmed that the tarballs appear in both areas
