perf scripts python: export-to-sqlite.py: Add support for pyside2

# provides LGPL-licensed Python bindings for Qt.  You will also need the package

# libqt4-sql-sqlite for Qt sqlite3 support.

#

# Examples of installing pyside:

#

# ubuntu:

#

#	$ sudo apt-get install python-pyside.qtsql libqt4-sql-psql

#

#	Alternately, to use Python3 and/or pyside 2, one of the following:

#

#		$ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql

#		$ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql

#		$ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql

# fedora:

#

#	$ sudo yum install python-pyside

#

#	Alternately, to use Python3 and/or pyside 2, one of the following:

#		$ sudo yum install python3-pyside

#		$ pip install --user PySide2

#		$ pip3 install --user PySide2

#

# An example of using this script with Intel PT:

#

#	$ perf record -e intel_pt//u ls

# difference is  the 'transaction' column of the 'samples' table which is

# renamed 'transaction_' in sqlite because 'transaction' is a reserved word.
