Brad Fitzpatrick c3736ae41a Dockerfile: use our own Go toolchain, not the golang Docker image ...

The golang:N-alpine Docker image lags behind Go minor releases by a
day or two. When we bump go.mod to a new minor version before the
image catches up, the required "Build Docker image" CI check fails
with "go.mod requires go >= 1.27.1 (running go 1.27.0;
GOTOOLCHAIN=local)" and blocks the toolchain bump from merging.

Instead, base the build stage on plain alpine and download the
Tailscale Go toolchain release for the revision in go.toolchain.rev,
matching how everything else in this repo is built.

Fixes #21072
