stages/grub2: option to install EFI data

Browse source 
Add support for copying EFI data from the build root. If
`uefi.install` is set to `true`, `BOOT` and `uefi.vendor`
directories will be copied from the build root. This is
useful for example on OSTree based systems where boot/efi/EFI
is not being populated by an RPM package; but it can be used
also on other systems where it is not desirable to deliver
the EFI data via packages.
