perf scripts python: exported-sql-viewer.py: Fix warning display

Deprecation warnings are useful only for the developer, not an end user.
Display warnings only when requested using the python -W option. This
stops the display of warnings like:

 tools/perf/scripts/python/exported-sql-viewer.py:5102: DeprecationWarning:
         an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag).
         Implicit conversion to integers using __int__ is deprecated, and
         may be removed in a future version of Python.
    err = app.exec_()

Since the warning can be fixed only in PySide2, we must wait for it to
be finally fixed there.
