agent: Enable kata-cc-rustls-tls in image-rs

- Enable the kata-cc-rustls-tls feature in image-rs, so that it
can get resources from the KBS in order to retrieve the registry
credentials.
- Also bump to the latest image-rs to pick up protobuf fixes
- Add libprotobuf-dev dependency to the agent packaging
as it is needed by the new image-rs feature
- Add extra env in the agent make test as the
new version of the anyhow crate has changed the backtrace capture thus unit
tests of kata-agent that compares a raised error with an expected one
would fail. To fix this, we need only panics to have backtraces, thus
set RUST_BACKTRACE=0 for tests due to document
https://docs.rs/anyhow/latest/anyhow/

Fixes #9538
