The tailscale/gokrazy-kernel module was a fork of rtr7/kernel that
stalled at Linux 6.8.9 (July 2024). All of the kernel config options we
had added in that fork (ENA, Xen for EC2, virtio-mmio for qemu microvm,
virtio RNG, IPv6 policy routing, netlink diag, etc) are now present in
the gokrazy project's own gokrazy/kernel.amd64 module, which tracks
current kernel.org releases (Linux 7.1.3 as of this change) and is the
gokrazy project's supported kernel for x86_64 PCs and VMs.
Switch the tsapp and natlabapp images, the natlab VM tests, and the
CI workflow to gokrazy/kernel.amd64, drop the tailscale/gokrazy-kernel
dependency, and update gokrazy/kernel.arm64 to latest while here.
Verified with TestEasyEasy, TestJustIPv6, and TestTailscaleSSH in
tstest/natlab/vmtest with --run-vm-tests.

Move the appliance/AMI build logic into tailscale.com/gokrazy/build so
Go callers (e.g. flash-appliance) can call it directly instead of
driving build.go over --json. build.go is now a thin flag wrapper; flags
and --json output are unchanged. Package-level state becomes a Builder
with an exported Config, ctx-first steps, and a Build one-shot.

Make build.go drivable and consumable by a CI builder. --json prints one
machine-readable result line to stdout while all logs/progress go to stderr,
so scripts can capture data cleanly. --region (honoring $AWS_REGION, default
us-east-1) pins import+register deterministically. AMI names derive from git:
<app>-<tag> on a tagged commit, else <app>-<describe>-<unixtime>.

We previously had two GOARCH variants for natlab testing
(gokrazy/natlabapp and gokrazy/natlabapp.arm64), but we didn't have
those variants for the "tsapp" (production, not testing) variant.
This adds arm64 for tsapp too. But there are two major users of arm64
for gokrazy: Raspberry Pis, and cloud VMs. So make two variants.
