package/sqlcipher: force libopenssl

v3.2.0 has a bug in the configure step which causes it to fail when being
built against libressl. As libopenssl is selected as the default, the
autobuilders have not uncovered this failure. The issue has been confirmed
in LTS 2018.02.10 (probably broken prior to that as well) and is not
related to the Openssl bump to 1.1.x.
