fix(ci): add safe.directory for git in CI containers

[maxamillion]

Summary

• Fix build-srpm.sh failing with "Not in a git repository" in CI containers
• Root cause: git refuses to operate on directories owned by a different user when running as root in containers
• Adds git config --global --add safe.directory before the git repo check

This fixes all RPM Repository workflow runs which have been failing since the workflow was introduced.

Test plan

• Verify RPM Repository workflow passes the "Build SRPMs" step
• Verify full workflow completes including aarch64 builds

📝 Walkthrough

Walkthrough

The build script adds a Git configuration command to mark the repository root as a trusted "safe directory" before executing subsequent git operations. This suppresses ownership/safety errors and allows the script to run in restricted environments where Git enforces ownership checks.

Poem

🐰 Hop-hop, git channels we align,
Marking repos as safe and fine,
No ownership errors to fight,
Safe directories shine so bright,
Scripts now build through the night! ✨
