Commit pre-generated test_verify certs

These can be re-generated via:

        cd test/certs; ./setup.sh

if need be.  The keys are all RSA 2048-bit keys, but it is possible
to change that via environment variables.

    cd test/certs
    rm -f *-key.pem *-key2.pem
    OPENSSL_KEYALG=rsa OPENSSL_KEYBITS=3072 ./setup.sh

    cd test/certs
    rm -f *-key.pem *-key2.pem
    OPENSSL_KEYALG=ecdsa OPENSSL_KEYBITS=secp384r1 ./setup.sh

    ...

Keys are re-used if already present, so the environment variables
are only used when generating any keys that are missing.  Hence
the "rm -f"
