crypto: add a nettle cipher implementation

Browse source 
If we are linking to gnutls already and gnutls is built against
nettle, then we should use nettle as a cipher backend in
preference to our built-in backend.

This will be used when linking against some GNUTLS 2.x versions
and all GNUTLS 3.x versions.
