Bump facil.io version (#3461)

Hi,

A new version of facial was released and this PR updates to the latest
version (0.6.1).

This version includes some logic changes that might effect the
benchmark as well as bug fixes (that shouldn’t effect the benchmark, as
they were mostly Websocket and pub/sub related).
