ipn: apply ControlURL policy before login

Browse Source 
Unlike most prefs, the ControlURL policy needs to take effect before
login. This resolves an issue where on first start, even when the
ControlURL policy is set, it will generate a login URL to the Tailscale
SaaS server.

Updates tailscale/coral#118
Fixes #10736
