Subject: [PATCH] Always docker/build.sh with --no-cache.

 * Almost every docker container starts with apt-get install foo bar
 * This is inherently not cacheable, meanwhile the lack of --no-cache
   has bitten nearly everyone I've talked to who's tried to rebuild.
 * Adding now to address this repeated problem.
