MAINTAINERS: A new maintainer for the qtests

Since I blundered into becoming the maintainer of the new functional
test  framework in QEMU (tests/functional/) recently, I need to drop
some other duties - it's getting too much for me otherwise. Laurent
is also quite busy with other projects nowadays, so I looked around
for help.
Fabiano did quite a lot of work in the qtests in the past already,
and is also already a maintainer for migration, so I thought he
would be a very good fit, thus I asked him whether he would be
interested to help out with the qtests and he agreed.
Thank you very much, Fabiano!
