sandbox: Allow utility process to access the log file on Windows

Currently this is only allowed for renderer and gpu process. This CL
also allows it for utility process.

Also pass logging switches to the UtilityProcessHost. These switches
are already passed in ServiceUtilityProcessHost. Both are using
kUtilityProcess process type.
