Gotta catch 'em all

Version 3 and before were missing versioned packages from homebrew, for example openssl@1.1. As of version 4, all openssl and libressl versions will have root PEMs created.

Version 3 and before were running c_rehash after installing certs.pem. This operation was not related to the installation of the roots, and will no longer be performed. Users that need to hash certs from etc/{openssl,libressl}/certs should perform the hashing themselves.
