runtime: program with deadlock doesn't fail if use -race flag

Go version: 1.8.3
OS: Mac

Program:
```go
package main

func main() {
	ch1 := make(chan int)
	<-ch1
}
```

if run with `go run deadlock.go` see: `fatal error: all goroutines are asleep - deadlock!`

if run with `go run -race deadlock.go` program never finish

Is it expected behavior?
Does it make sense to improve deadlock detector to be aware about race detector?
