[PATCH 3/3] grub-shell: Add $GRUB_QEMU_OPTS to run.sh to easily see unofficial QEMU arguments

[Glenn Washburn <development@efficientek.com>]

When re-running a failed test, even the non-standard grub-shell QEMU
arguments should be preserved in the run.sh to more precisely replay the
failed test run.
