perf script python: Add Python3 support to stackcollapse.py

Support both Python2 and Python3 in the stackcollapse.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
