    ci: Add job for pushing coverity reports
    
    This job does:
    1. Download the coverity bundle and untar it in a cached location
    2. Build GNOME Shell using clang and the coverity tool
    3. Compress the coverity report
    4. Upload for analysis
    
    In a similar setup to that of Mutter.
