Commit: 4dd4c54ccb1e41e37ef7708376ae1f2ca28712cf
 Email: davidjames@chromium.org

Fix race condition by using different symlinks for factory images.

Both the tests and archive_build read and write the latest symlink.
This CL fixes a race condition in archive_build by moving away from
using the latest symlink in archive_build.

BUG=chromium-os:18967
TEST=Run release cbuildbot archive_build on x86-mario-release.
     Verify it completes successfully and that latest symlink
     is unchanged now.
