rG685a78570b35: random: remove hifn(4)

Summary

The Hifn 7955 & 7956 only supports deprecated & NIST disallowed
algorithms (NIST SP800-224idp): SHA1 and SHA1-HMAC.

Furtermore the entropy RNG of the Hifn 7751, 7951, 7811, 7955,
and 7956 has no NIST Entropy Source Validation (ESV) certificate
and cannot be used in a FIPS-140-3 nor Common Criteara environment.

Furtermore the most prolific instance for FreeBSD was the
Soekris Engineering vpn1201, vpn1211, vpn1401, and vpn1411
offerings. These are all 32-bit only processors. The i386
kernel was de-supported in 15.0.

As with safe(4), FreeBSD itself has not yet deprecated SHA1 and SHA1-HMAC, but I think the hardware is ancient.
