crypto: s390/sha256 - rename module to sha256-s390

When the s390 SHA-256 code is built as a loadable module, name it
sha256-s390.ko instead of sha256.ko.  This avoids a module name
collision with crypto/sha256.ko and makes it consistent with the other
architectures.

We should consider making a single module provide all the SHA-256
library code, which would prevent issues like this.  But for now this is
the fix that's needed.
