    gnome-keysign-sign-key: Add binary mode for Python 3 compatibility
    
    Opening the file in binary mode is necessary for Python 3
    compatibility, otherwise it will fail with:
    "TypeError: arg 2: expected gpg.Data, file, bytes (not string!), or an
    object implementing the buffer protocol. Got: str"
    
    I also removed the unused sleep import.
