If HAX is running, don't print to stderr

Studio will highlight all stderr output as error in the IDE.
This minor change separates the success from the failure message
to stdout and stderr respectively.

There are even questions in stack overflow that mention
"HAX is working and emulator runs in fast virt mode" as the error.
