    wic: isoimage-isohybrid: add grubefi configfile support
    
    The latest wic kickstart refactoring introduced a bootloader option
    "--configfile" which lets wks' specify a custom grub.cfg for use
    while booting. This is very useful for creating stuff like boot menus.
    
    This change lets isoimage-isohybrid use --configfile; if this option is
    not specified in a wks, it generates a default cfg as before.
