go/analysis/passes/structtag: ignore warning if tag should be ignored

Having a private field with a json tag does not necessary means the
field needs to be exposed publicly. This change ignores the warning of
such fields that contain a json tag with the field tag "-".

The lines added in the unit tests will fail without these changes with
the error:
```
a/a.go:36:2: unexpected diagnostic: struct field b has json tag but is not exported
```
