    <sys/un.h>: Stop including <sys/file.h>.
    
    It is no longer needed since f635d1746140d0f4915af3adb8314f4759377d3b.
    
    While here, remove a forward declaration of struct sockopt (no longer
    needed since 002c1265bf9676475d08e73e8d873cea9ee4a82e) and adjust a
    bit of whitespace.
    
    Also adjust ng_ksocket.c where DragonFly specific code was assuming
    that including <sys/un.h> would bring in <sys/fcntl.h>.
