Handle disk space issues - try multiple temp directories and fallback gracefully

- Try multiple temp directory locations (/tmp, /var/tmp, /root, /root)
- Clean up old temporary directories before creating new ones
- Skip git clone if no temp directory can be created
- Try multiple locations for fallback installer download
- Better error messages for disk space issues
