Verify that the AES-128 is used for encrypting the local CA
OpenSSL by default used very old defaults, RC2-CBC and 3DES, for
encryption. This resulted in a credential that was unusable if
FIPS was enabled.
Both values are now hardcoded to AES-128-CBC so that it is both
more modern and will work in all situations. This tests that
nothing has changed.
