Subject: [PATCH 6/7] perf script python: Add addr into perf sample dict

From: Leo Yan <leo.yan@...aro.org>

ARM CoreSight auxtrace uses 'sample->addr' to record the target address
for branch instructions, so the data of 'sample->addr' is required for
tracing data analysis.

This commit collects data of 'sample->addr' into perf sample dict,
finally can be used for python script for parsing event.
