updates tailscale/tailscale#13476 On darwin, os.Hostname is no longer reliable when called from a sandboxed process. To fix this, we will allow clients to set an optional callback to query the hostname via an alternative native API. We will leave the default implementation as os.Hostname since this works perfectly well for almost everything besides sandboxed darwin clients. Signed-off-by: Jonathan Nobels <jonathan@tailscale.com>
