config, Configure: move the check of removed crypto/ sub-systems

The 'config' script checked for a bunch of crypto/ sub-system
directories, and added 'no-' options if they weren't there.

We move it to 'Configure' in an effort to simplify 'config' for
further work.

Note: this is pretty much a historical thing.  In modern OpenSSL, it's
much simpler to edit the SUBDIRS statement in crypto/build.info.
However, it's been claimed the there are those who still remove some
of these sub-system sources.
