Disconnect the dependency on the kernel package from the runtime
package.  There are a number of problems here:

 1) The runtime package installed into a chroot or a jail would
    include the kernel package, changing the behavior of how jails
    work now [1];

 2) As result of (1), it is possible a binary may incorrectly
    resolve kernel symbols [2]; in addition, it is possible there
    will be unexpected fallout with 32-bit jails on a 64-bit host
    kernel [2].
