[Buildroot] [PATCH v2 8/8] linux: new Image.gz format for aarch64

[Erico Nunes <nunes.erico@gmail.com>]

Distributions such as Fedora use the Image.gz image format for aarch64
to be booted with grub. It exists in linux since v3.10.

This was not in v1.
It is actually an independent patch from the rest of the grub2 changes
but is somewhat related as this is probably the image format to be used
with grub2 for aarch64.
