I don't think these calls were ever doing anything useful since
rpki-client always needed a libressl version with automatic library
initialization thanks to CMS.

When we still used cryptoerrx() & friends, the strings would be loaded
before first use. Similarly for lookups of ciphers and digests by name
(which we never used to my knowledge).
