MAINTAINERS: Remove myself as Avocado Framework reviewer

While I was very enthusiastic when Avocado was presented to
the QEMU community and pushed forward to have it integrated,
time passed and I lost interest. Be honest, remove my R: tag
to not give fake expectation I'd review patches related to
Avocado anymore.
