Subject: [PATCH] ttyd: add backport patch for ssl issue on firefox

If ttyd is configured to ssl, you will get the following message in the
log `refuse to serve WS client for illegal ws path`. Upstream a patch
has already been applied which fixes this.

Since there is no newer version than 1.6.1, this fix is backported as a
patch. And could be removed if a new version of ttyd is available.
