cros_boot_mode: make cros_debug bootloader argument prempt others
cros_debug was meant to be a replacement for cros_* to force
developer mode behavior - such as on legacy firmware. However,
the easiest way to do so without modifying a file is to add the
argument to the bootloader during boot. With syslinux, it is
appended. That means that a cros_legacy commandline will have
cros_debug appended. Since order matters, moving cros_debug
up the chain allows it to preempt any other values.
