configure: Move check for <gnutls/crypto.h> 

Checking for the availability of this header, just like checking
for the availability of gnutls_rnd(), requires CFLAGS and LIBS to
be set appropriately.

Fixes the following compilation errors on FreeBSD:

  qemu/qemu_domain.c:640:16: error: implicit declaration of function
   'gnutls_rnd' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
      if ((ret = gnutls_rnd(GNUTLS_RND_RANDOM, key, nbytes)) < 0) {
                 ^
  qemu/qemu_domain.c:640:27: error: use of undeclared identifier
   'GNUTLS_RND_RANDOM'; did you mean 'GNUTLS_CRD_ANON'?
      if ((ret = gnutls_rnd(GNUTLS_RND_RANDOM, key, nbytes)) < 0) {
                            ^~~~~~~~~~~~~~~~~
                            GNUTLS_CRD_ANON
