Brad Fitzpatrick d3efe8caf6 safesocket, ipn/ipnserver: look up peer creds on Darwin
And open up socket permissions like Linux, now that we know who
connections are from.

This uses the new inet.af/peercred that supports Linux and Darwin at
the moment.

Fixes #1347
Fixes #1348

Brad Fitzpatrick 54d0d83b67 safesocket: on Linux, make /var/run/tailscale be 0755
Continuation of earlier two umask changes,
5611f290eb and
d6e9fb1df0.

This change mostly affects us, running tailscaled as root by hand (wit
a umask of 0077), not under systemd. End users running tailscaled
under systemd won't have a umask.

Brad Fitzpatrick 5611f290eb ipn, ipnserver: only require sudo on Linux for mutable CLI actions
This partially reverts d6e9fb1df0, which modified the permissions
on the tailscaled Unix socket and thus required "sudo tailscale" even
for "tailscale status".

Instead, open the permissions back up (on Linux only) but have the
server look at the peer creds and only permit read-only actions unless
you're root.

In the future we'll also have a group that can do mutable actions.

On OpenBSD and FreeBSD, the permissions on the socket remain locked
down to 0600 from d6e9fb1df0.

David Anderson 4460bd638b safesocket: simplify API.
On unix, we want to provide a full path to the desired unix socket.

On windows, currently we want to provide a TCP port, but someday
we'll also provide a "path-ish" object for a named pipe.

For now, simplify the API down to exactly a path and a TCP port.
