crash-reporter: Add udev rule to collect cyapa trackpad logs
Add the udev rule that when trackpad driver cyapa detects abnormal
behavior and fired uevent, additional logs from system logs are
collected.
BUG=chromium-os:35169
TEST=Made fake cyapa uevent and checked that logs are generated
in /var/spool/crash
