tools lib traceevent: Fix strerror_r() use in pevent_strerror
glibc-2.16 starts to mark the function with attribute warn_unused_result
so that it can cause a build warning.
Since GNU version of strerror_r() can return a pointer to a string
without setting @buf, check the return value and copy/truncate it to our
buffer if needed.
