Bug: FFmpeg Build Failures Due to Checksum Validation Issues

The FFmpeg download and caching logic has a couple of issues that can cause builds to fail. If the remote checksum download fails, a newly fetched 'latest' archive is incorrectly validated against an outdated cached checksum. Separately, if the archive name isn't found in the checksum file, the file can be corrupted, preventing successful validation.
