Instead of logging lsof execution failures to stdout,
incorporate them into the returned error.
While we're here, make it clear that the file
success case always returns a nil error.

This allows the test to be run inside a mounted filesystem,
which I'm doing now as a I develop on a linux VM.
Fixes#2367.

Without this, `tailscale status` ignores the --socket flag on macOS and
always talks to the IPNExtension, even if you wanted it to inspect a
userspace tailscaled.

Previously the CLI could only find the HTTP auth token when running
the CLI outside the sandbox, not like
/Applications/Tailscale.app/Contents/MacOS/Tailscale when that was
from the App Store.

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.

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.

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.

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.
