Josh Bleecher Snyder 0807e3e2f7 syncs: disable TestWatchMultipleValues on Windows CI builds
The Windows CI machine experiences significant random execution delays.
For example, in this code from watchdog.go:

done := make(chan bool)
go func() {
	start := time.Now()
	mu.Lock()

There was a 500ms delay from initializing done to locking mu.

This test checks that we receive a sufficient number of events quickly enough.
In the face of random 500ms delays, unsurprisingly, the test fails.

There's not much principled we can do about it.
We could build a system of retries or attempt to detect these random delays,
but that game isn't worth the candle.

Skip the test.
