We have cases where the SetControlClientStatus would result in
a Shutdown call back into the auto client that would block
forever. The right thing to do here is to fix the LocalBackend
state machine but thats a different dumpster fire that we
are slowly making progress towards.
This makes it so that the SetControlClientStatus happens in a
different goroutine so that calls back into the auto client
do not block.
Also add a few missing mu.Unlocks in LocalBackend.Start.

As a fallback to package managers, allow updating tailscale that was
self-installed in some way. There are some tricky bits around updating
the systemd unit (should we stick to local binary paths or to the ones
in tailscaled.service?), so leaving that out for now.

Instead of trying to use the user config dir, and then fail back to the
OS temp dir, just always use the temp dir. Also use a filename that is
less likely to cause collisions.
This addresses an issue on a test synology instance that was
mysteriously failing because there was a file at /tmp/tailscale. We
could still technically run into this issue if a
/tmp/tailscale-web-csrf.key file exists, but that seems far less likely.

While investigating the fix in 7538f38671,
I was curious why the testwrapper didn't fail. Turns out if the test
times out and there was no explicit failure, the only message we get
is that the overall pkg failed and no failure information about the
individual test. This resulted in a 0 exit code.
This fixes that by failing the explicit case of the pkg failing when
there is nothing to retry for that pkg.

So even if the server doesn't support sending patches (neither the
Tailscale control server nor Headscale yet do), this makes the client
convert a changed node to its diff so the diffs can be processed
individually in a follow-up change.
This lets us make progress on #1909 without adding a dependency on
finishing the server-side part, and also means other control servers
will get the same upcoming optimizations.
And add some clientmetrics while here.

Top-level Version in pkgs response is not always in sync with SPK
versions, especially on unstable track. It's very confusing when the

to 1.49.y.
Instead, grab the SPK-specific version field.
