llama stack build not working for CONTAINER_BINARY podman with UBI9 base image.

[vamsi-01]

System Info

Fedora linux OS to run llama stack build command.

Information

• [x] The official example scripts
• [ ] My own modified scripts

🐛 Describe the bug

When building the llama stack using build.yaml with a ubi9/* base image, the intermediate Containerfile will include a RUN instruction to install the necessary packages: https://github.com/meta-llama/llama-stack/blob/main/llama_stack/distribution/build_container.sh#L95-L107

Building the custom image using the above generated Containerfile fails because the dnf command requires root or sudo privileges to execute.

Expected behavior

The build should be successful for ubi9/* base images without any permission errors.
