Subject: [PATCH] libs: libwebsockets: add latest released version

This includes a patch for cyassl building that has been committed
upstream, but not released.

There's no SPDX license identifier for LGPL + static linking exception,
so I've used "LGPL-2.1+exception" as suggested at
http://lwn.net/Articles/378329/
