[PATCH RFC] MAINTAINERS: add TRACE EVENT LIBRARY section

[Lukas Bulwahn <lukas.bulwahn@gmail.com>]

The git history shows that the files under ./tools/lib/traceevent/ are
being developed and maintained by Tzetomir Stoyanov and Steven Rostedt
and are discussed on the linux-trace-devel list.

Add a suitable section in MAINTAINERS for patches to reach them.

This was identified with a small script that finds all files only
belonging to "THE REST" according to the current MAINTAINERS file, and I
acted upon its output.

Ceco, Steven, I added the information based on what I could see from an
outsider view. Please change and more files to the entry if needed.

applies cleanly on current master and next-20200131

Ceco, congrats becoming a kernel maintainer :)
