    pygrub/grub: always use integer for default entry
    
    The original code set the default to either a string or an integer
    (0) and relies on a Python 2 specific behaviour to work (integer is
    allowed to be compared to string in Python 2 but not 3).
    
    Always use integer. The caller (pygrub) already has code to handle
    that.
