Ilya Leoshkevich 9a12adc704 linux-user/s390x: Fix unwinding from signal handlers 
Commit 31330e6cec ("linux-user/s390x: Implement setup_sigtramp")
removed an unused field from rt_sigframe, disturbing offsets of other
fields and breaking unwinding from signal handlers (e.g. libgcc's
s390_fallback_frame() relies on this struct having a specific layout).
Restore the field and add a comment.
