Remove old versions of autotest-tests and autotest-deps.

This CL is copied from:
https://gerrit.chromium.org/gerrit/#/c/61600

To speed up the build, we are splitting the autotest-tests and
autotest-deps packages into a few other packages. This may cause
conflicts so we will need to uninstall the other packages first. This
migration script will take care of the uninstallation.
