Two bug fixes:
1. when tailscale update is executed as root, `os.UserCacheDir` may
return an error because `$XDG_CACHE_HOME` and `$HOME` are not set;
fallback to `os.TempDir` in those cases
2. on some weird distros (like my EndeavourOS), `/usr/sbin` is just a
symlink to `/usr/bin`; when we resolve `tailscale` binary path from
`tailscaled`, allow `tailscaled` to be in either directory

The Sparkle-based update is not quite working yet. Make `NewUpdater`
return `ErrUnsupported` for it to avoid the proliferation of exceptions
up the stack.

This commit changes the PostureChecking syspolicy key to be a
PreferenceOption(user-defined, always, never) instead of Bool.
This aligns better with the defaults implementation on macOS allowing
CLI arguments to be read when user-defined or no defaults is set.

Log some progress info to make updates more debuggable. Also, track
whether an active update is already started and return an error if
a concurrent update is attempted.
Some planned future PRs:
* add JSON output to `tailscale update`
* use JSON output from `tailscale update` to provide a more detailed
status of in-progress update (stage, download progress, etc)

The flags are hidden for now. Adding propagation to tailscaled and
persistence only. The prefs field is wrapped in a struct to allow for
future expansion (like update schedule).

ScrubbedGoroutineDump previously only returned the stacks of all
goroutines. I also want to be able to use this for only the current
goroutine's stack. Add a bool param to support both ways.

Exposes some internal state of the sockstats package via the C2N and
PeerAPI endpoints, so that it can be used for debugging. For now this
includes the estimated radio on percentage and a second-by-second view
of the times the radio was active.
Also fixes another off-by-one error in the radio on percentage that
was leading to >100% values (if n seconds have passed since we started
to monitor, there may be n + 1 possible seconds where the radio could
have been on).

Otherwise there may be a panic if it's nil (and the control side of
the c2n call will just time out).

Switch to using logtail for logging sockstat logs. Always log locally
(on supported platforms), but disable automatic uploading. Change
existing c2n sockstats request to trigger upload to log server and
return log ID.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

This lets the control plane can make HTTP requests to nodes.
Then we can use this for future things rather than slapping more stuff
into MapResponse, etc.
