Adding package information to ELF objects

Ability to connect to public debuginfo servers is not guaranteed at all times. Machines can be isolated from the internet for security reasons. Or the VM/container setup may simply not have configured public network access in general. Or it could be in a semi-broken state where network temporarily isn't working properly. Or the admin have explicitly blocked access to debuginfo servers for privacy reasons. Or the software may not actually be from Fedora. If this concept gets supported across many distros, then binaries from e.g. a Debian container running on Fedora host can be handled, without having to know about a Debian debuginfo server, or a debuginfo server for every distro (if one even exists)
