cmake: Fix unbound config compile settings

Browse source 
This allows the OpenSSL function checks to compile in unbound's CMake
configuration.

Otherwise, the functions SHA256() and EVP_sha512() won't be called from
libunbound as possible algorithms.

They had not been compiling because static OpenSSL libraries were being
used, along with lack of -ldl. The static library preference is
unnecessary for the checks, so use default suffixes ordering for
CMAKE_FIND_LIBRARY_SUFFIXES when building unbound.
