Subject: [PATCH] split wrong-script-interpreter into env-script-interpreter

For mere mortals, details message for wrong-script-interpreter
does not explain why the env as shebang is an issue. Splitting
that case into a separate diagnostic allows a more detailed
info message alongside that gives a better rationale.
