#1684331 — [PATCH] scripts/package: snap-pkg target

Following in footsteps of other targets like 'deb-pkg, 'rpm-pkg' and 'tar-pkg',
this patch adds a 'snap-pkg' target for the creation of a Linux kernel snap
package using the kbuild infrastructure.

A snap, in its general form, is a self contained, sandboxed, universal package
and it is intended to work across multiple distributions and/or devices. A snap
package is distributed as a single compressed squashfs filesystem.

A kernel snap is a snap package carrying the Linux kernel, kernel modules,
accessory files (DTBs, System.map, etc) and a manifesto file.  The purpose of a
kernel snap is to carry the Linux kernel during the creation of a system image,
eg. Ubuntu Core, and it's subsequent upgrades.

For more information on snap packages: https://snapcraft.io/docs/

Is this something a user could do with the existing deb target, and
then running deb2snap?

No, the kernel snap is a special case, it requires communication with
the store (e.g. to download the core snap) and some extra steps,
therefore you should use snapcraft and abstract from these details.
