Update go.toolchain.rev for https://github.com/tailscale/go/pull/104 and add a test that, when using the tailscale_go build tag, we use the right Go toolchain. We'll crank up the strictness in later commits. Updates #13527 Change-Id: Ifb09a844858be2beb144a420e4e9dbdc5c03ae3a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
