Subject: [PATCH] jenkins/toolchains: fetch DIGESTS file to allow reusing
 downloaded SDK as seed

The catalyst build uses the same SDK version as seed as the current SDK, but
will only reuse the cached tarball if a DIGESTS file exists and is correct.
Prefetch this file to prevent the build from trying to access google storage
anonymously.
