   On posix system, running this function before starting replay fixes a
   bug that shows up when Telemetry is run as a background command from a
   script. https://crbug.com/254572.
 
   Background: Signal masks on Linux are inherited from parent
   processes. If anything invoking us accidentally masks SIGINT
   (e.g. by putting a process in the background from a shell script),
   sending a SIGINT to the child will fail to terminate it.
