Brad Fitzpatrick 4afc189919 wgengine/router: make Linux delRoute idempotent, cidrDiff fail late as possible ...

This makes cidrDiff do as much as possible before failing, and makes a
delete of an already-deleted rule be a no-op. We should never do this
ourselves, but other things on the system can, and this should help us
recover a bit.

Also adds the start of root-requiring tests.

TODO: hook into wgengine/monitor and notice when routes are changed
behind our back, and invalidate our routes map and re-read from
kernel (via the ip command) at least on the next reconfig call.

Updates tailscale/corp#1338
