hkbd(4): add some extra handy fn key bindings

Browse Source 
- Fn+S for ScrollLock as it's very useful to have ScrollLock on
  FreeBSD's TTY.
- Fn+P for PrtSc/SysRq, as it's another very handy but sadly missing
  key on Macbooks.
- Some other Fn+<key> combinations duplicating existing keys.

Apply the change to ukbd(4) as well.
