Revert "Put EdDSA back as approved algorithms."

This reverts commit 09627a8.

NIST isn't allowing EdDSA at this stage after all, so flag it as not
FIPS approved in the FIPS provider.  Guidance for FIPS 140-3 is expected
later this month:

    The use of EdDSA still remains non-approved.

    Before the FIPS 186-5 and SP 800-186 algorithms / curves can be
    used in the approved mode, the CMVP will need to do (at least)
    the following:

    * Incorporate FIPS 186-5 and SP 800-186 into SP 800-140C/D;

    * Update IG 10.3.A to incorporate self-test requirements for the
      new algorithms/curves.

    * Write a new IG on this transition to clarify the issues raised in
      this thread and elsewhere and provide a clear transition schedule.

    The CMVP is working on all three of these items and hope to have
    drafts public by the end of March.

    Since security relevant changes are not permitted for new 140-2
    submissions, and under the assumption that this transition away
    from FIPS 186-4 algorithms will be 'soft' and not move modules to
    the historical list, we do not plan on writing 140-2 guidance for
    this transition.

It seems unlikely that all of these requirements will be completed before
we submit.
