    Remove snd_aureal driver source
    
    This driver was not finished when it was committed in 1999 and was never
    connected to the build.
    
    A version of the driver used to be available in ports as
    audio/aureal-kmod, but it has been removed.  It did not build on FreeBSD
    10.x or later and the binary objects it required were not available
    after Google Code disappeared.
