[Bug 1624485] [NEW] Nettle: Enable AES-NI instructions on amd64.

Public bug reported:

The current build of libnettle6 does not have AES-NI enabled. There's
two configure options for enabling it:

--enable-x86-aesni: Use AES-NI instructions instead of the standard implementation. This will break on systems that don't have AES-NI.
--enable-fat: Build a "fat" library that has the standard implementation and the AES-NI implementation. This allows the library to continue working on older systems while providing faster performance on systems that have AES-NI.

Note that Nettle's AES-NI implementation as of v3.2 is only supported on
amd64, not i386, so this would only affect the 64-bit package.

** Affects: nettle (Ubuntu)
