tools: remove in tree libaio

We have defaulted to using the system libaio for a while now and I din't think
there are any relevant distros which don't have it that running Xen 4.4 would
be reasonable on.

Also it has caused confusion because it is not ever wanted on ARM, but the
build system doesn't express that (could be fixed, but deleting is the right
thing to do anyway).

-.SH DESCRIPTION
-When dealing with asynchronous operations it is sometimes necessary to
-get into a consistent state.  This would mean for AIO that one wants to
-know whether a certain request or a group of request were processed.
-This could be done by waiting for the notification sent by the system
-after the operation terminated, but this sometimes would mean wasting
-resources (mainly computation time). 
-.PP
-Calling this function forces all I/O operations operating queued at the
-time of the function call operating on the file descriptor
-.IR "iocb->io_fildes"
-into the synchronized I/O completion state .  The 
-.IR "io_fsync"
-function returns
-immediately but the notification through the method described in
-.IR "io_callback"
-will happen only after all requests for this
-file descriptor have terminated and the file is synchronized.  This also
-means that requests for this very same file descriptor which are queued
-after the synchronization request are not affected.
-.SH "RETURN VALUES"
-Returns 0, otherwise returns errno.
-.SH ERRORS
-.TP
-.B EFAULT
-.I iocbs
-referenced data outside of the program's accessible address space.
-.TP
-.B EINVAL
-.I ctx
-refers to an unitialized aio context, the iocb pointed to by 
-.I iocbs
-contains an improperly initialized iocb, 
-.TP
-.B EBADF
-The iocb contains a file descriptor that does not exist.
-.TP
-.B EINVAL
-The file specified in the iocb does not support the given io operation.
