fix(ci): add --privileged to mock RPM build containers

[maxamillion]

Summary

• Mock requires mounting tmpfs inside its chroot, which fails without
  privileged container access
• Add --privileged to x86_64 container jobs and aarch64 run-on-arch-action
  dockerRunArgs in both rpm-repo.yml and ci.yml

Test plan

• Verify all 6 RPM build jobs (3 x86_64 + 3 aarch64) pass the mock build
  step
• Verify RPM Repository workflow completes and publishes to GitHub Pages

📝 Walkthrough

Walkthrough

Two GitHub Actions workflow files have been modified to enable privileged container execution for RPM build jobs. Both the standard and aarch64 build variants now run with elevated privileges.

Changes

Cohort / File(s)	Summary
CI Workflow .github/workflows/ci.yml	Added options: --privileged to the rpm-build job container configuration and injected --privileged into the dockerRunArgs for the aarch64 variant.
RPM Repository Workflow .github/workflows/rpm-repo.yml	Added options: --privileged to the build-rpms job container configuration and injected --privileged into the dockerRunArgs for the aarch64 cross-build step.

Poem

🐰 Elevated privileges granted, the containers now run free,
Building RPMs with power, both x86 and aarch64 with glee,
No more permission denied, the workflows now shine bright,
Privileged mode enabled—let's build through the night! ✨
