OpenSSL now installs a CMake config, but it is not generated by CMake,
and it is not multi-config capable. This limitation affects location
properties, interface link libraries and package variables.
This PR just patches the config to chainload CMake's Find module.
Together with vcpkg's cmake wrapper, this immediately gives the desired
imported targets in a multi-config configuration when a user really
requests `OpenSSL CONFIG`.
