tailscale: networking breaks when it is stopped or disabled

Description tailscale will generate an /etc/resolv.conf file for its use.  If you quit the service, its resolv.conf will still be in effect, loaded but it will be invalid. Cure

If you saved your resolv.conf prior to working with tailscale, you can restore it, or create a new one similar to below.

  nameserver 127.0.0.1   nameserver 10.0.0.1   #nameserver 192.168.1.1   #nameserver 8.8.4.4   options edns0   #search localnetworkname

Some lines commented out but could be used if you wish.  Check man 5 resolver for more details.
