[OE-core] [PATCH] grub/grub-efi: fix conflict for aach64

[changqing.li at windriver.com]

From: Changqing Li <changqing.li at windriver.com>

MACHINE = qemuarm64
IMAGE_INSTALL_append = ' grub grub-efi'

do_rootfs failed with error:
file /usr/lib64/grub/arm64-efi/acpi.module conflicts between attempted installs of grub-2.02-r0.aarch64 and grub-efi-2.02-r0.aarch64
file /usr/lib64/grub/arm64-efi/adler32.module conflicts between attempted installs of grub-2.02-r0.aarch64 and grub-efi-2.02-r0.aarch64
...
file /usr/lib64/grub/arm64-efi/zfsinfo.module conflicts between attempted installs of grub-2.02-r0.aarch64 and grub-efi-2.02-r0.aarch64

For arm64, grub and grub-efi both compiled GRUBD2 with platform
arm64-efi, arm64 only support platform efi. So both packages have
almost same folder and content /usr/lib64/grub/arm64-efi/*

if Machine set to qemux86_64, do_rootfs will not have this problem,
since for grub, it compiled with platform i386-pc, for grub-efi,
compiled with platform x86-64-efi.

    grub/grub-efi: fix conflict

    While installing grub and grub-efi, there are conflict files
    in ${sysconfdir} ${datadir} ${bindir} ${sbindir}.

    - Since all of the conflicted files are tools which is
      common for grub and grub-efi, we split them (except
      grub-editenv) to grub-common in grub.

common tools for grub and grub-efi are installed into grub-common,
for aarch64, also shipped libdir into this common packages.
in this way, for qemuarm64, package grub is empty, and package grub-efi
use lib in package grub-common
