As part of the work on #7248 I wanted to know all of the flags on the RouteMessage struct that we get back from macOS. Though it doesn't turn out to be useful (when using an exit node/Tailscale is the default route, the flags for the physical interface routes are the same), it still seems useful from a debugging/comprehensiveness perspective. Adds additional Darwin flags that were output once I enabled this mode. Signed-off-by: Mihai Parparita <mihai@tailscale.com>
