Only build compatfd when using AIO and make sure to always init AIO

OpenBSD doesn't use AIO so don't try to build compatfd when not using AIO.

Also make sure to call qemu_aio_init() from bdrv_init.  Everything that uses
bdrv calls bdrv_init so it makes sense to init aio from there instead of
in every single tool.
