Replace configure option --with-openssl-dir (#14028)

This is a leftover from the refactoring of the --with-openssl-dir option
that once accepted the path to OpenSSL but wasn't renamed back then.

Instead of --with-openssl-dir, SSL support in ext/ftp and ext/mysqlnd
can be enabled implicitly when building with ext/openssl enabled
(--with-openssl) or explicitly by using new separate configure options
--with-ftp-ssl and --with-mysqlnd-ssl.
