The following patches add support for signed UEFI kernel images on
arm64. The first three patches are for the linux patches and the last
two are for linux-signed.

The patches are complicated a bit by the fact that our arm64 generic
kernels are gzip compressed. We wish to keep the kernels we install
compressed both in the linux-image and linux-image-unsigned packages,
however signing must be done on the uncompressed kernel image. Therefore
we decompress the kernel when adding it to the signing tarball and
recompress it when building linux-signed.
