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
-.B io_submit
-submits
-.I nr
-iocbs for processing for a given io context ctx.
-
-The 
-.IR "io_submit"
-function can be used to enqueue an arbitrary
-number of read and write requests at one time.  The requests can all be
-meant for the same file, all for different files or every solution in
-between.
-
-.IR "io_submit"
-gets the 
-.IR "nr"
-requests from the array pointed to
-by 
-.IR "iocbs"
-.  The operation to be performed is determined by the
-.IR "aio_lio_opcode"
-member in each element of 
-.IR "iocbs"
-.  If this
-field is 
-.B "IO_CMD_PREAD"
-a read operation is enqueued, similar to a call
-of 
-.IR "io_prep_pread"
-for this element of the array (except that the way
-the termination is signalled is different, as we will see below).  If
-the 
-.IR "aio_lio_opcode"
-member is 
-.B "IO_CMD_PWRITE"
-a write operation
-is enqueued.  Otherwise the 
-.IR "aio_lio_opcode"
-must be 
-.B "IO_CMD_NOP"
-in which case this element of 
-.IR "iocbs"
-is simply ignored.  This
-``operation'' is useful in situations where one has a fixed array of
-.IR "struct iocb"
-elements from which only a few need to be handled at
-a time.  Another situation is where the 
-.IR "io_submit"
-call was
-canceled before all requests are processed  and the remaining requests have to be reissued.
-
-The other members of each element of the array pointed to by
-.IR "iocbs"
-must have values suitable for the operation as described in
-the documentation for 
-.IR "io_prep_pread"
-and 
-.IR "io_prep_pwrite"
-above.
-
-The function returns immediately after
-having enqueued all the requests.  
-On success,
-.B io_submit
-returns the number of iocbs submitted successfully.  Otherwise, -error is return, where 
-error is one of the Exxx values defined in the Errors section.
-.PP
-If an error is detected, then the behavior is undefined.
-.PP
-Simultaneous asynchronous operations using the same iocb produce
-undefined results.
-.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.
