From: "Tan, Shaopeng" <tan.shaopeng@xxxxxxxxxxxxxx>
In kselftest framework there is a limited time for each sub test,
when the time limit comes SIGTEM signal will be sent to sub test by
"timeout --foregroup <seconds>" command.
In resctrl_tests, fork() is used to create a child process.
This commit ensures child process to be killed before parent process
exiting if SIGTERM signal comes.
