Fix: relayd: send_viewer_streams sends stack data in padding

A single stack-allocated instance of `struct lttng_viewer_stream` is
used to send the various streams to the live viewer. This structure
contains a path and channel name which remain uninitialized beyond the
null terminator.

The structure is zeroed on every iteration.
