Fix: install AWS CLI v2 standalone to avoid Python conflicts

The apt-installed awscli v1 conflicts with the newer botocore pulled in
by pip (via redisbench-admin), causing KeyError: 'opsworkscm' on every
aws s3 cp call.

Fix by installing AWS CLI v2 as a standalone binary (no Python dependency),
and add set -euo pipefail to bm_files.sh so download failures are caught
immediately instead of silently producing missing files.
