    build: fix build of virt-login-shell on systems with older gnutls
    
    On systems where gnutls uses libgcrypt, I'm seeing the following
    build failure
    
    libvirt.c:314: error: variable 'virTLSThreadImpl' has initializer but incomplete type
    libvirt.c:319: error: 'GCRY_THREAD_OPTION_PTHREAD' undeclared here (not in a function)
    ...
    
    Fix by undefining WITH_GNUTLS_GCRYPT in config-post.h
