Revert Author <jallison@ciq.com>
Revert Commit fd8a0de.
Revert Reason: This changes the default DRBG back to HMAC SHA512 to
keep entropy certifications for all Rocky9.6 FIPS modules.
Approved by the lab.
Keeping hmac(sha512) allows the entropy certificates used
for Rocky 9.2 FIPS to be re-used in 9.6, preventing re-certification
of all the kernel and userspace modules.
NB. We still get the scalability speedup from the per-CPU DRBG
changes.
