Respect user-defined exit signal in clone() and clone3()
...
When calling clone() and clone3(), the user is allowed to specify a
signal to be sent to the parent process on exit. Respect this value by
storing it in the Process struct and sending the signal on exit.
Add a test as well to verify that the signal is properly delivered to
the parent.
