MAINTAINERS: Volunteer to maintain Darwin-based hosts support

While I am not an experienced Darwin OS user, I now have to
use a macOS based workstation and alike CI, meaning I should
easily spot regressions and test fixes. I therefore volunteer
to collect Darwin related patches and keep QEMU in good state
on macOS, and to some extent iOS.
