Patch to add in identification of /dev/xvd? devices (Xen)

Here's an example of trying to install grub on a Xen VBD:

# grub-install /dev/xvdg
expr: non-integer argument
/dev/xvda1 does not have any corresponding BIOS drive.
#

The problem is a goofy regular expression in grub-install, which accounts for 'sd*', 'hd*', and several other block device types, but doesn't handle 'xvd*'.

This change resolves the issue:

I have not tested this on Gentoo.  I found this in a bug report for Arch Linux.  Linked here:  https://bugs.archlinux.org/task/30241

To be fair I have not tested the above patch at all.  This patch is directly from the Arch Linux website so I am not 100% certain if anything needs to be changed to make this compatible with Gentoo.

You probably want xen-pvgrub with Xen instead of grub.

grub:0 is gone
