Brad Fitzpatrick 0a10a5632b cmd/tailscaled: add TS_DEBUG_BACKEND_DELAY_SEC for testing async startup
This adds an envknob to make testing async startup more reproducible.
We want the Windows GUI to behave well when wintun is not (or it's
doing its initial slow driver installation), but during testing it's often
too fast to see that it's working. This lets it be slowed down.

Updates #6522
