Add touch_noise_feedback to feedback report

We have a daemon touch_noise_monitor that monitors touch noise
and dumps related logs to /var/log/touch_noise.log.
This patch adds the touch_noise.log to feedback report.

BUG=chrome-os-partner:16788
TEST=Make fake /var/log/touch_noise.log
     Run sysinfo_script_runner, and make sure entry "touch-noise"
     has the right content.
