disable UsageStats in FIPS mode

UsageStatistics is so close to being FIPS-140 compliant but fails at the
last hurdle.

We can not encrypt with RSA but we can perform key wrap.  The output does
separate the key and data, by creating a new Key for encrypting the data
and that key is encrypted with RSA.  If only the RSA cipher was created with
Cipher.WRAP_MODE (or Cipher.UNWRAP_MODE) instead of CIPHER.ENCRYPT_MODE (or
CIPHER.DECRYPT_MODE) we would be fine, alas it is not and changing this
would mean a change on the backend and to be able to continue to support
both whilst older versions are in the wild.

The goal of JEP-237 is not to fix all non compliant issues, so here we
just ensure that in FIPS mode the usage statistics are disabled.
