vfs: Remove aio_linux

Triggered by https://bugzilla.samba.org/show_bug.cgi?id=13128 I think this module should go. Once Linux aio will do what Samba needs, this might be worth another look. What we should instead do soon is support Linux preadv2 and the RWF_NOWAIT flag to avoid the thread context switch whenever possible.

+vfs_aio_linux module removed
+============================
+
+The current Linux kernel aio does not match what Samba would
+do. Shipping code that uses it leads people to false
+assumptions. Samba implements async I/O based on threads by default,
+there is no special module required to see benefits of read and write
+request being sent do the disk in parallel.
