Build: Update rollup and other dev deps

Reviewed output of `node build/review-package.js 2.17.1` after a build.

The only difference affecting our code is a change in the internal
`_iterableToArrayLimit` helper from Babel:

```diff
   function _iterableToArrayLimit(arr, i) {
-    var _i = arr && (typeof Symbol !== "undefined" && arr[Symbol.iterator] || arr["@@iterator"]);
+    var _i = arr == null ? null : typeof Symbol !== "undefined" && arr[Symbol.iterator] || arr["@@iterator"];
```
