Remove explicit util dependency.

`assert` depended on the userland `util` module rather than browserify's
builtin, which could cause two different versions of `util` could be
included in bundles, if browserify's version doesn't exactly match
`assert`'s dependency.

Since `util` is builtin in Node and in bundlers, we can safely use it
instead of explicitly depending on it.
