slugos: move to ixp4xx-kernel, change nslu2 to more generic ixp4xx in conf

 - rather than build nslu2-kernel or nas100d-kernel slugos-image now
   builds ixp4xx-kernel, the generic kernel.  ixp4xx is now used as the
   normal MACHINE override, even though MACHINE itself is still set to
   nslu2 or nas100d (or ixp4xx).
