Bug#681227: [PATCH] Allow bootdev to be "dummy"

[Matt Kraai <kraai@ftbfs.org>]

The workaround for 681227 prevents grub-installer from trying to
install to devices that don't exist.  This breaks installations on
systems that use grub-efi or grub-yeeloong, since they set the device
to "dummy".  This patch fixes the workaround to allow this value.
