  [SystemZ] [Sanitizer] Bugfixes in internal_clone().

The __flags variable needs to be of type 'long' in order to get sign extended
properly.

internal_clone() uses an svc (Supervisor Call) directly (as opposed to
internal_syscall), and therefore needs to take care to set errno and return
-1 as needed.
