s390x/tcg: make STFL store into the lowcore
Using virtual memory access is wrong and will soon include low-address
protection checks, which is to be bypassed for STFL.
STFL is a privileged instruction and using LowCore requires
!CONFIG_USER_ONLY, so add the ifdef and move the declaration to the
right place.
This was originally part of a bigger STFL(E) refactoring.
