[libvirt] [PATCH 08/10] Move virCacheKernel enum implemetation from conf/ to util/

[Martin Kletzander]

It will be used in that file later on, plus it makes sense for all the
implementations to be in same place.  Also comment each one of them nicely and
add a comment explaining why they all need to end with the same _LAST value.
