Subject: [PATCH] Increase make parallelism and remove unnecessary sudo

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).
