[TRE-2374] Add libopenssl package

openssl 1.0.2 is part of public SDK, so we need backward compatibility,
platform image must provide openssl in both versions 1.0.2 & 1.1.1
to keep applications binary compatibility.
Previously openssl 1.0.2 was added to platform image by dependencies,
but since all platform components are migrated to openssl 1.1.1
we need to add openssl 1.0.2 statically.
