Alex Brainman 9985b3f1ed wgengine/monitor: close closeHandle
eccc167 introduced closeHandle which opened the handle,
but never closed it.

Windows handles should be closed.

I used the Windows APIs wrong previously, but it had worked just
enough.

Brad Fitzpatrick 22c462bd91 wgengine/monitor: fix copy/paste-o to actually monitor route changes
Due to a copy/paste-o, we were monitoring address changes twice, and
not monitoring route changes at all.

Verified with 'tailscale debug --monitor' that this actually works now (while
running 'route add 10.3.0.0 mask 255.255.0.0 10.0.0.1' and 'route delete (same)'
back and forth in cmd.exe)

In practice route changes are accompanied by address changes and this
doesn't fix any known issues. I just noticed this while reading this
code again. But at least the code does what it was trying to do now.

Brad Fitzpatrick 24d1a38e81 wgengine/monitor: add a poller to the Windows link change monitor
The poller is slow by default, but speeds up for a bit after a network
change, in case WPAD/PAC files are still loading.
