CMake: Export and install library targets.

The configs can be consumed by setting LibreSSL_DIR to the build
directory, or after installation using CMAKE_PREFIX_PATH/LibreSSL_DIR.

For compatibility, the EXPORT_NAME of targets and the LIBRESSL_*
variables are set to match the names used in FindLibreSSL.
