sha/asm/keccak1600-s390x.pl: resolve -march=z900 portability issue.



Negative displacement in memory references was not originally specified,
so that for maximum coverage one should abstain from it, just like with
any other extension. [Unless it's guarded by run-time switch, but there
is no switch in keccak1600-s390x.]
