MAINTAINERS: take over vboxsf from Hans de Goede

I talked to Hans de Goede about two weeks ago in person. He expressed he
would rather have someone else maintain vboxsf and was thinking about
orphaning it. Since I am already doing filesystem stuff anyway, I am
fine with doing this. (vboxsf is a thin layer between the vfs and the
Virtual Box guest device driver).

I have no major plans for vboxsf, but I do want to support passing
physical addresses to the host; the communication protocol seems to
allow for it and it would mean we can get rid of some kmap calls.
