This allows sending logs from the "logpolicy" package (and associated
callees) to something other than the log package. The behaviour for
tailscaled remains the same, passing in log.Printf

On some platforms (notably macOS and iOS) we look up the default
interface to bind outgoing connections to. This is both duplicated
work and results in logspam when the default interface is not available
(i.e. when a phone has no connectivity, we log an error and thus cause
more things that we will try to upload and fail).
Fixed by passing around a netmon.Monitor to more places, so that we can
use its cached interface state.

We are seeing indications that some devices are still getting into an
upload loop. Bump logInterval in case these devices are on slow
connections that are taking more than 3 seconds to uploads sockstats.

Split apart polling of sockstats and logging them to disk. Add a 3
second delay before writing logs to disk to prevent an infinite upload
loop when uploading stats to logcatcher.

This change focuses on the backend log ID, which is the mostly commonly
used in the client. Tests which don't seem to make use of the log ID
just use the zero value.

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.
