Subject: [PATCH 31/37] perf script python: Add Python3 support to net_dropmonitor.py

From: Tony Jones <tonyj@...e.de>

Support both Python2 and Python3 in the net_dropmonitor.py script

There may be differences in the ordering of output lines due to
differences in dictionary ordering etc.  However the format within lines
should be unchanged.

The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6
