kernel selection menu to the beastie menu. List of kernels is taken from
`kernels' in loader.conf(5) as a space (or comma) separated list of names
to display (up to 9). If not set, default value is "kernel kernel.old".
Does not validate that kernels exist because the next enhancement will be
to allow selection of the root device.
Discussed on: -current
MFC after: 3 days
submenus. See menusets.4th(8) for additional details including examples.

This change does not alter the appearance or user experience, only enhances
