cmake: Allow user to select bundled zlib Under some circumstances the installed / system version of zlib may not be desirable due to being too old or buggy. This patch adds the option `USE_BUNDLED_ZLIB` that will cause the bundled version of zlib to be used. We may also want to add similar functionality to allow the user to select other bundled 3rd-party dependencies instead of using the system versions. /cc @pks-t @ethomson
