go/parser: fix example to run on the playground

Browse Source 
The example shouldn't rely on the existance of example_test.go. That
breaks in the playground, which is what the "run" button in
https://golang.org/pkg/go/parser/#example_ParseFile does.

Make the example self-sufficient by using a small piece of source via a
string literal instead.

Fixes #19823.
