[PATCH 1/3] trace-cmd: Replace PySting_FromString() with PyUnicode_FromString()

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Python 3 has deprecated PyString_FromString(), but both Python 2 and
Python 3 have PyUnicode_FromString() which should be equivalent (at least
according to google). As Python 2 is going to be EOL soon, we need to
support Python 3.
