Remove definitions from Kernel canonical names.

Before: Canonical names contained pointers to the corresponding Kernel
tree which assumed that the whole tree was in memory whenever the
canonical names were.

Now: Canonical names do not contain these pointers.  They were only
really used to perform name-based lookup in the VM's heap so the
canonical name itself is enough.

If we later find that we need to get from a canonical name to its
Kernel tree we can add an offset in the binary (for instance) to the
canonical name or in a separate mapping on the side.
