tracing: Fix output of set_event for some cached module events
The following works fine:
~# echo ':mod:trace_events_sample' > /sys/kernel/tracing/set_event
~# cat /sys/kernel/tracing/set_event
*:*:mod:trace_events_sample
~#
But if a name is given without a ':' where it can match an event name or
system name, the output of the cached events does not include a new line:
~# echo 'foo_bar:mod:trace_events_sample' > /sys/kernel/tracing/set_event
~# cat /sys/kernel/tracing/set_event
foo_bar:mod:trace_events_sample~#
Add the '\n' to that as well.
