[libvirt] [PATCH] security: fix DH key generation when FIPS mode is on

When FIPS mode is on, gnutls_dh_params_generate2 will fail if 1024 is
specified as the prime's number of bits, a bigger value works in both
cases.

with the development version of GNU TLS is possible to test FIPS mode
setting the env variable GNUTLS_FORCE_FIPS_MODE=2
