[PATCH] grub-install: Install PV Xen binaries into the upstream specified path

[Ian Campbell <ijc@hellion.org.uk>]

Upstream have defined a specification for where guests ought to place their
xenpv grub binaries in order to facilitate chainloading from a stage 1 grub
loaded from dom0.

http://xenbits.xen.org/docs/unstable-staging/misc/x86-xenpv-bootloader.html

The spec calls for installation into /boot/xen/pvboot-i386.elf or
/boot/xen/pvboot-x86_64.elf.
