testlib: Don't filter unprintable characters when targeting TTY 

QAbstractTestLogger::outputString() helpfully tries to filter out
unprintable characters, but if the QT_MESSAGE_PATTERN includes
escaped ANSI sequences this just results in removing the escape
code and outputting the ANSI sequence vebose, e.g ?[34

Convenience method to write \a msg to the output stream.
The output \a msg must be a \c{'\0'}-terminated string (and not \nullptr).
A copy of it is passed to \l filterUnprintable() and the result written to
the output \c stream, which is then flushed.
If the output \c stream is TTY the message is printed as is. If not, the
message is filtered via filterUnprintable() first. In both cases the output
\c stream is flushed after printing.
