crypto: require gnutls >= 3.1.18 for building QEMU

Browse source 
gnutls 3.0.0 was released in 2011 and all the distros that are build
target platforms for QEMU [1] include it:

  RHEL-7: 3.1.18
  Debian (Stretch): 3.5.8
  Debian (Jessie): 3.3.8
  OpenBSD (ports): 3.5.18
  FreeBSD (ports): 3.5.18
  OpenSUSE Leap 15: 3.6.2
  Ubuntu (Xenial): 3.4.10
  macOS (Homebrew): 3.5.19

Based on this, it is reasonable to require gnutls >= 3.1.18 in QEMU
which allows for all conditional version checks in the code to be
removed.
