    gnome-session-inhibit: fix child cmd arguments
    
    int execvp(const char *file, char *const argv[]);
    The execv(), execvp(), and execvpe() functions provide an array of pointers
    to null-terminated strings that represent the argument list available to the
    new program. The first argument, by convention, should point to the filename
    associated with the file being executed.
    
    In the above paragraph "The first argument" is argv[0] (not the first
    parameter of the execvp function).
