webpack: Use `require` to look for olm 

Since https://github.com/matrix-org/matrix-js-sdk/pull/141, the jenkins build
does pull in the olm module, but because it's using npm v2, buries it deep in
node_modules. Rather than using the `fs` module to hunt for it, just try to
`require` it in the webpack config.
