Maisem Ali d24a8f7b5a wgengine/router{windows}: return the output from the firewallTweaker
on error.

While debugging a customer issue where the firewallTweaker was failing
the only message we have is `router: firewall: error adding
Tailscale-Process rule: exit status 1` which is not really helpful.
This will help diagnose firewall tweaking failures.
