Improve caching, linter compliance, and runtime image sizes. Notable image size reductions: - syscallbench: 160MB drop (~250 MB -> ~90 MB) by converting to a multi-stage build (AS build) to strip gcc and build tools from the runtime image. - absl: 80MB drop (665MB -> 486MB) by combining Bazel installer download, execution, and cleanup into a single RUN layer. - build-grpc : 450MB drop (1.38GB -> 830MB) by removing temporary bazel-*.sh installer scripts from intermediate layers and adding --no-install-recommends. - tensorflow: 60MB (1.29GB -> 1.23GB) drop by clearing /var/lib/apt/lists/* cache. - util: 56MB (137MB -> 81MB) by clearing apt cache lists.
