Fix nfpm package building by using relative paths and running from working directory

- Changed nfpm configuration to use relative paths for content sources
- Run nfpm from the working directory to resolve relative paths correctly
- Place nfpm.yaml in the working directory instead of out directory
- Fix cleanup to remove config file from correct location

This fixes the issue where nfpm couldn't find the files to package.
