MAINTAINERS: mark MGLRU as maintained

The three folks being added here are actively working on MGLRU within
Google, so we can review patches for this feature and plan to contribute
some improvements / extensions to it on an ongoing basis.

With three of us we may have some hope filling Yu Zhao's shoes, since he
has moved on to other projects these days.
