[strongSwan] Which version of openssl to use with strongswan

Yeah, that repository is not really maintained anymore (the version in
it is too old anyway, Google would reject an app with it when uploading
to Play).  We currently use BoringSSL (see [1]).  If you want to use
OpenSSL you'd have to port a newer version yourself.
