Again, a regression when moving from 11.10 to 12.04 (precise pangolin).

The attached patch solves the problem, as usual.

Title:
  Error activating XKB configuration with MacBook keyboard model

Bug description:
  Binary package hint: xkb-data

  I've got Intrepid installed on a MacBookPro5,1 with German keyboard
  layout. I started configuring the keyboads using gnome-keyboard-
  properties as available from the settings menu. I first selected the
  layout "Germany Macintosh, eliminate dead keys" and followed that up
  with changing the model to "MacBook/MacBook Pro (Intl)". This resulted
  in an error message "Error activating XKB configuration" which asked
  me to prvide this additional information:

  $ xprop -root | grep XKB
  _XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "pc105", "de", "mac_nodeadkeys", ""
  _XKB_RULES_NAMES(STRING) = "evdev", "pc105", "de", "mac_nodeadkeys", ""

  $ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
   layouts = []
   model = macbook79
   options = []

  As the error message from the dialog contains little actual
  information, I straced gnome-settings-daemon and identified a failing
  invocation of xkbcomp as the likely cause of the issue. By renaming
  /usr/bin/xkbcomp and replacing it with a wrapper script, I managed to
  get my hands on its input file and reproduce the issue:

  $ cat /tmp/fileJPMGgA 
  xkb_keymap {
          xkb_keycodes  { include "evdev+aliases(qwertz)" };
          xkb_types     { include "complete+numpad(mac)" };
          xkb_compat    { include "complete" };
          xkb_symbols   { include "pc+macintosh_vndr/de(mac_nodeadkeys)+inet(evdev)" };
          xkb_geometry  { include "macintosh(macbook79)" };
  };

  $ xkbcomp -I -I/usr/share/X11/xkb -xkm /tmp/fileJPMGgA /tmp/fileNtKqh7
  Error:            No Symbols named "mac_nodeadkeys" in the include file "macintosh_vndr/de"
                    Exiting
                    Abandoning symbols file "(null)"

  That looks like a much better error description. Looking at
  /usr/share/X11/xkb/symbols/macintosh_vndr/de I see that indeed it
  doesn't contain a description of "mac_nodeadkeys". Neither does it
  include /usr/share/X11/xkb/symbols/de where the mac_nodeadkeys would
  have been defined. Changing the layout to simple "Germany Eliminate
  dead keys", I could use the MacBook keyboard model all right, just as
  mac_nodeadkeys layout worked all right with a Generic keyboard model.
  However, both combinations don't fully match the key labels.

  My first concern is that for an obvious choice like a MacBook keyboard
  model with a mac keyboard layout, no obscure error messages should be
  generated by the Gnome UI. Secondly, it would be nice to actually get
  Mac keyboard layout, in order to stay consistent with OS X and
  friends.
