[PATCH] trust: allow to also add openssl style hashes to pem-directory

For backward compatibility with older openssl and other libs like
gnutls /etc/ssl/certs needs to be created as pem-directory rather
than openssl-directory on openSUSE. Therefore also allow to install
openssl style hashes there to avoid having to call c_rehash with a
script.
