dlt_user_shared: Add timeout to writev (#385)
This timeout is necessary to prevent
blocking writev indefinitely.
Without the timeout dlt-daemon, may block
indefinitely when an app id is re-used
very frequently.
In that case dlt-daemon won't accept anymore
new connections and further communication
in any way is not possible anymore.
