Ilya Leoshkevich 5356ba1ff4 s390/bpf: Fix unwinding past the trampoline 
When functions called by the trampoline panic, the backtrace that is
printed stops at the trampoline, because the trampoline does not store
its caller's frame address (backchain) on stack; it also stores the
return address at a wrong location.

Store both the same way as is already done for the regular eBPF programs.
