tracing: Add Masami Hiramatsu as co-maintainer

Masami has been maintaining kprobes for a while now and that code has
been an integral part of tracing. He has also been an excellent reviewer
of all the tracing code and contributor as well.

The tracing subsystem needs another active maintainer to keep it running
smoothly, and I do not know anyone more qualified for the job than Masami.

Ingo has also told me that he has not been active in the tracing code for
some time and said he could be removed from the TRACING portion of the
MAINTAINERS file.
