Simplify configuration of HAVE_GNUTLS3 etc.

There's only one GnuTLS, so configuring these symbols at
'configure' time is overkill.  Simplify things by moving their
configuration to src/gnutls.h (Bug#27708).
* configure.ac (HAVE_GNUTLS3, HAVE_GNUTLS3_HMAC, HAVE_GNUTLS3_AEAD)
(HAVE_GNUTLS3_CIPHER, HAVE_GNUTLS3_DIGEST): Move these definitions
from here ...
* src/gnutls.h: ... to here, and simplify.
