Skip filtering outside FIPS mode. We need this because openssl's
    DH_check() takes a long time to run when FIPS is disabled -- it
    won't filter by a predefined list then, but instead applies
    safe-prime checks. These typically add up to several minutes of
    run time for the default moduli file.
