fix(ci): move aarch64 repo preparation inside QEMU container

[maxamillion]

Summary

• The 'Prepare repo directory' step ran on the Ubuntu host which lacks createrepo_c (exit code 127)
• Moved repo prep + createrepo_c into the run-on-arch-action run block
• Volume-mount output directory so the upload step can access the built repo

Test plan

• Verify aarch64 RPM builds complete and the repo artifact is uploaded

📝 Walkthrough

Walkthrough

The build-rpms-aarch64 job consolidates RPM build output handling and repository generation into a single container step. Container volume mounts change from /rpms to /output. The separate "Prepare repo directory" step is removed, merging its logic into the unified build step. Repository generation now occurs inside the container, and artifact upload paths are updated accordingly.

Summary

GitHub Actions RPM Build Workflow .github/workflows/rpm-repo.yml

Consolidates RPM build output handling and repository generation into a single container step in the build-rpms-aarch64 job. Container volume mount changes from ${{ github.workspace }}/rpms → /rpms to ${{ github.workspace }}/output → /output. Removes separate "Prepare repo directory" step. Adds in-container directory creation, RPM copying, debug info stripping, and createrepo_c execution. Updates artifact upload path from repo/ to output/repo/.
