Add SHA256 Signatures for RPMs

[twa16]

Hello, we are attempting to leverage Falco in an environment where SHA256 hashes are required for RPM signatures.

With the current RPMs, we are unable to install directly from the repository. I should be able to add it to the builds scripts if there is interest.
