Brad Fitzpatrick 0433cc6929 feature/syslog, cmd/tailscaled, logpolicy: add optional --syslog flag ... Add a new modular syslog feature providing a tailscaled --syslog flag that sends the daemon's logs to the system syslog daemon instead of stderr, which is useful when running as a daemon without a service manager that captures stderr (e.g. OpenWrt's procd). The feature package registers two new hooks: one to register its flag before flag parsing, and one that tailscaled calls early in main to redirect the standard library's default logger. Because logpolicy later points the default logger at logtail, whose local console copy writes to stderr, logpolicy now also consults the hook and sends its console copy to the same sink (with timestamps disabled, as syslog records its own). The feature is linked by default only on Linux, FreeBSD, and OpenBSD, and can be removed with the ts_omit_syslog build tag. If connecting to the syslog daemon fails at startup, tailscaled logs a warning and continues logging to stderr.
