Subject: Use cutelogger for Rockbox Utility internal trace.

Change tracing from qDebug() to use cutelogger, which is available under the
LGPL2.1. This allows to automatically add filename and line number to the log,
and also provides multiple log levels.

Change-Id: I5dbdaf902ba54ea99f07ae10a07467c52fdac910
