afb-proto-ws: Fix autolock in proto-ws

Because a systemd event loop can not be reentered
while evaluating an event callback, the event loop
was removed from the threads. It had the effect to
enter in deadlock when calling a synchronous call
while in an event callback.

Queueing a job solves the issue.

But because using queued job has implications on
libafbws, a fake job manager is added for libafbws.
