Subject: perf script python: Add Python3 support to export-to-sqlite.py
Origin: https://git.kernel.org/linus/ebf6c5c181abe9309788c6241d39602a1ce18723
Bug-Debian: https://bugs.debian.org/944641
Support both Python2 and Python3 in the export-to-sqlite.py script
The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6
