package/libopenssl: move options

package/libopenssl: move options

Since e3159cad71 (package/libopenssl: move target arch selection
to Config.in), we have a Config.in that contains a few options to
configure libopenssl (openSSL, the original).

As such, it makes sense to move the remaining options there too.

We also move the condition there, mimicking what is done for the
external toolchains' options too.
