gnutls: Updated (2.10.3 -> 2.12.3) (see note!)

Note:

Since 2.11.x gnutls is supporting 2 cryptographic backend libraries:
1. nettle (default)
2. libgcrypt

The gnutls package within opensde was changed to reflect those changes.
As nettle is the official default crypto library we only enable gcrypt
support if nettly is not available.
