crypto: sha3-generic - Use __optimize to support old compilers
With gcc-4.1.2:
crypto/sha3_generic.c:39: warning: ‘__optimize__’ attribute directive ignored
Use the newly introduced __optimize macro to fix this.
Fixes: 83dee2ce1ae791c3 ("crypto: sha3-generic - rewrite KECCAK transform to help the compiler optimize")
