Setting gnutls to use nettle instead of libgcrypt

[Totony]

Oops, I said "nettle is linked to gnutls", but I meant "gnutls is linked to
nettle".

So, gnutls have no reason to use libgcrypt ? (Even if the program that uses
gnutls link libgcrypt ?)
I think I will fill a bug report to the package (it's not normal that aria2
is linked to libgcrypt if it uses gnutls, is it ?).
