[Qemu-devel] [PATCH 1/2] trace: Remove trailing newline in events

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

While the tracing frawework does not forbid trailing newline in
events format string, using them lead to confuse output.
It is the responsibility of the backend to properly end an event
line.

Some of our formats have trailing newlines, remove them.
