Bug 1332554

+++ This bug was initially created as a clone of Bug #1329129 +++

Description of problem:
                                                                                                         
In the current runner framework we always return the pid i.e ret value of the waitpid, as said above it is not the exit value of the child process

Version-Release number of selected component (if applicable):
mainline

Actual results:
returning the ret value of waitpid()

Expected results:
extract the exit code and return the actual exit status of the child process

    runner: extract and return actual exit status of child
    
    Intro:
    pid_t waitpid(pid_t pid, int *status, int options);
    
    The waitpid() system call suspends execution of the calling process
    until a child specified by pid  argument has  changed  state.
    
    Here the ret (pid) value is not equal to the exit status of the child process.
    Check manpages for more info on this.
    
    Problem:
    In the current runner framework we always return the pid i.e ret value
    of the waitpid, as said above it is not the exit value of the child process
    
    Solution:
    Extract the actual exit code/status in case if the child terminated normally,
    that is, by calling exit(3) or _exit(2), or by returning from main()
