Subject: [PATCH] crosutils: move factory setup scripts to
 ../platform/factory-utils/factory_setup

This CL is the counter part of https://gerrit.chromium.org/gerrit/11190

For creating portable factory archives and simplify scripts folder, we should
move all factory scripts to a tandalone folder. Symlink is set to ease
transition until we've updated all factory documents.

archive_factory was designed for creating bundle so not required anymore.
make_universal_factory_shim and mk_memento_images are only invoked by
make_factory_packages, so they're also simply removed without symlinks.

BUG=chrome-os-partner:5979
TEST=./make_factory_package.sh --config PATH_TO_CONFIG # pass
