1. Increase make parallelism from -j4 to -j$(nproc): Use all available CPU cores instead of hardcoded 4 jobs. This significantly reduces compilation time for large dependencies like Node.js (from ~1h15m to potentially <30m), reducing exposure to worker infrastructure issues. 2. Remove sudo from apt-get in python recipe: Build containers run as root, so sudo is unnecessary and may cause issues. Changes apply to both cflinuxfs4 and legacy recipe paths. Part of fix for Node.js LTS build failures in buildpacks-ci dependency-builds pipeline (#29-#33).
