Configure NTL without NTL_LEGACY_SP_MULMOD=on

[jpflori]

There is an issue with bernmm which prevents this.
For every even number from 128, the result of

bernoulli(n, algorithm='bernmm')

is wrong.

This is because some modular multiplication mod n is made with inputs larger than n which is not supported by NTL (as documented).
