Implement vfork system call
...
It's implemented by making it issue clone system call internally with
the arguments of (SIGCHLD, 0, 0, 0, 0). The feature in which the caller
of vfork blocks until the child issues exit/execve is not implemented.
Refer to #233 .

ptrace: add error stub to prevent mcexec from waiting
...
In LTP's ptrace03 test,
there is a exit() preceded by ptrace(PTRACE_TRACEME).
In this case, processes will be usually finished immediately.
But mcexec will fall into waiting for parent's ptrace(PTRACE_CONT),
because mcexec sends itself a signal in processing of exit().
