This adds support for Gokrazy GAF (Gokrazy Archive Format) zip
auto-updates, starting to wire up Tailscale's clientupdate mechanism
to Gokrazy's update mechanism.
Currently there's just a CLI command to update from a GAF URL,
with an --unsigned flag for use in a new natlab vmtest.
Next step would be publishing unstable track GAF files on
pkgs.tailscale.com, with detached signatures, and then making the
clientupdate mechanism also download those and check signatures.

Add natlabapp.arm64 config and gokrazydeps.go for building a gokrazy
natlab appliance image targeting arm64 (Apple Silicon). This is the
arm64 counterpart to the existing natlabapp (amd64) used by vmtest.
The arm64 image uses github.com/gokrazy/kernel.arm64 and is built
with "make natlab-arm64" in the gokrazy directory.

... rather than abusing the generic tsapp.
Per discussion in https://github.com/gokrazy/gokrazy/pull/275
It also means we can remove stuff we don't need, like ntp or randomd.
