metrics library: move event file location from /var/log to /var/run
The event file, which is used for communicating metric events
from chrome os to chrome, has been living in the very non-kosher
location /var/log/metrics/uma-events. This change duplicates it
in /var/run/metrics/uma-events. A later chrome change will pick
up the metrics from there.
I also opened crbug.com/373833 to remove the duplication once
Chrome has switched over.
