configure: Load fetcher plugins after crypto base plugins

Some fetcher plugins (such as curl) might build upon OpenSSL to implement
HTTPS fetching. As we set (and can't unset) threading callbacks in our
openssl plugin, we must ensure that OpenSSL functions don't get called after
openssl plugin unloading.

We achieve that by loading curl and all other fetcher plugins after the base
crypto plugins, including openssl.
