Remove or soften excess dependencies
    
    The alsa-utils dependencies were added to resolve directory ownership,
    but the plugins do not require the utils.  Instead, just have the
    plugins co-own /etc/alsa.
    
    The hard requires on JACK and PulseAudio daemons (nowadays both provided
    by PipeWire) are not strictly necessary, e.g. in flatpak builds where
    the host instance is used over a socket connection.
