Have 'named -V' report supported algorithms
These vary depending upon the version of OpenSSL in use and how OpenSSL is configured.
These may also depend on FIPS mode and crypto graphic engine configuration.
These may also depend on what is discovered at compile time.
e.g.
DNSSEC algorithms: RSASHA1 NSEC3RSASHA1 RSASHA256 RSASHA512 ECDSAP256SHA256 ECDSAP384SHA384 ED25519 ED448
DS algorithms: SHA-1 SHA-256 SHA-384
HMAC algorithms: HMAC-MD5 HMAC-SHA1 HMAC-SHA224 HMAC-SHA256 HMAC-SHA384 HMAC-SHA512
TKEY mode 2 support (Diffie-Hellman): yes
TKEY mode 3 support (GSS-API): yes
