MINOR: hlua: properly handle hlua_process_task HLUA_E_ETMOUT

In hlua_process_task: when HLUA_E_ETMOUT was returned by
hlua_ctx_resume(), meaning that the lua task reached
tune.lua.task-timeout (default: none),
we logged "Lua task: unknown error." before stopping the task.

Now we properly handle HLUA_E_ETMOUT to report a meaningful error
message.
