Remove the ripemd160 module.

The library code used by this module is licensed under a non-free
license which is incompatible with the GPLv2. Combined with the
fact that it has been superceded by better algorithms like bcrypt
I have decided to remove it.

An alternate implementation of this algorithm is provided by the
m_hash_gnutls module if people *really* need to use it.
