[PATCH v2 10/12] grub-shell: Only turn on qemu head when large debug value is specified

[Glenn Washburn]

There are several levels of debug and more may be added. But the qemu head
should be one of the highest debug levels. Set debug to a high value of 10
to turn on the head. We do not want to accidentally turn it on when adding
a new debug level to the testing system.
