Irrespectively of the discussion on checking this in configure,
there's another user of <sys/vfs.h> in fsdev/virtfs-proxy-helper.c.
I see in patch 13 that the helper won't be built on Darwin, but
this could change, and anyway, I'd like the handling of <sys/vfs.h>
to stay consistent across the VirtFS code.
