    dbusServices/screencast: Install unconditionally
    
    We currently decide at build time whether to include screencast
    support, based on whether the required gst/pipewire library headers
    are installed.
    
    That check is imprecise, because having the library headers available
    at build time doesn't necessarily mean that the libraries are there
    at runtime, or that the corresponding typelibs are installed.
    
    It makes more sense to check the requirements at runtime, so prepare
    for that by installing the screencast service unconditionally, but
    bail out early if the dependencies aren't met.
