Add missing break statement in chromeos path switch

Following https://codereview.chromium.org/1129863003/ which added
support for loading an apply an ICC file based on EDID product id a new
entry was added to the chromeos paths switch statement. Unfortunately
the break statement was missing in the newly added case.

Failing to break from the switch statement triggered a DCHECK failure in
path_service.cc which would result in in asserts in builds where DCHECK
is fatal.
