go/analysis/singlechecker: append a newline after "Flags:" 

Currently `flag.Usage` set in `Main` prints a message as follows,
```
⋮
Flags:  -V      print version and exit
⋮
```
but this should be
```
⋮
Flags:
  -V      print version and exit
⋮
```
It seems this is caused by [this](https://go-review.googlesource.com/c/tools/+/162717).
