configure.ac: Add checks for Nettle (Crypto library)

This patch adds configure.ac checks for the Nettle cryptography
library. It requires version 3.0 as it adds the aesctx256_ctx
structure to be used in a future commit. This check is also
an optional dependency as SIMPLE with NTLM auth and encryption
with the internal keyring, as are planned to use this, aren't
absolutely required.
