posix: Run key destructors during thread restart

POSIX key destructors must be called during thread restart.  Just like
the POSIX cleanup handlers.  This ensures that the TLS object
destructors are called during thread restart for example.  It is
important for the global construction, which uses a thread restart to
run the Init task in a clean environment.

Close #2689.
