trace: enforce that every trace-events file has a final newline

When generating the trace-events-all file, the build system simply
concatenates all the individual trace-events files. If any one of those
files does not have a final newline, the printf format string will have
the contents of the first line of the next file appended to it, which is
usually a '#' comment.
