Subject: [OE-core] [PATCH v2 1/2] grub_git: extend recipe for proper target     deployment

This extends the grub_git recipe so it can deploy grub
on the target boot disk just like grub-efi. Mainly
this copies stuff from the grub-efi recipe and then
adjusts some bits accordingly. This would allow
using the latest and greatest versions of grub
on the target.
