packaging: deprecate unzip and wget in Dockerfiles

[hahakiki2025]

Remove unzip and wget from Dockerfile as the latest Fluent Bit codebase no longer depends on these packages. They are legacy artifacts and are no longer required.

For Ubuntu dockerfile, removed unzip but kept wget as it's still invoked

Summary by CodeRabbit

• Chores
  • Updated build container package dependencies across CentOS, AlmaLinux, AmazonLinux, Debian, Ubuntu, Raspbian, and RockyLinux for both amd64 and ARM64 variants.
  • Package install lists were adjusted to remove unzip and to de-duplicate wget entries where they appeared multiple times, keeping the rest of the tooling dependency sets consistent.
