huddly-monitor is no longer able to power cycle huddly camera

Project Member Reported by darekm@chromium.org, Jun 19 2018 
While huddly-monitor attempts to power cycle camera now, it fails, producing the following in the logs:

WARNING huddly-monitor[1302]: Failed to disable power on USB port 1
WARNING huddly-monitor[1302]: Failed to hotplug.
ERR huddly-monitor[1302]: Monitor thread terminated due to failure.

This is because huddly-monitor needs write access to /sys/class/gpio/ which was removed with 66548622ec053e942931ff23132da8b1211eea87

  camera corretly.
