Let sunkbd(4) emulate an AT keyboard by default.

This has the following benefits:
- allows to use the AT keyboard maps in share/syscons/keymaps with
  sunkbd(4),
- allows to use kbdmux(4) with sunkbd(4),
- allows Sun RS232 keyboards to be configured and used the same
  way as Sun USB keyboards driven by ukbd(4) (which also does AT
  keyboard emulation) with X.Org, putting an end to the problem
  of native support for the former in X.Org being broken over and
  over again.
