[PATCH RFC] MAINTAINERS: clarify maintenance of nvdimm testing tool

[Lukas Bulwahn]

The git history shows that the files under ./tools/testing/nvdimm are
being developed and maintained by the LIBNVDIMM maintainers.

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.

Signed-off-by: Lukas Bulwahn <lukas.bulwahn@xxxxxxxxx>

This is a RFC patch based on what I could see as an outsider to nvdimm.
Dan, please pick this patch if it reflects the real responsibilities.

applies cleanly on current master and next-20200131
