    ci: Install mutter again on coverity job
    
    This job "needs" the build job and thus gets its artifacts, but
    it will not inherit the environment where we already installed
    Mutter in /usr. This apparently broke once there was a more
    recent mutter-clutter .pc file to look up.
    
    Install Mutter in /usr again in this job, so the new build for
    coverity finds all dependencies.
