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).
