rules/compat: remove the incomplete and faulty rules for Dvorak layouts

They are incomplete because, for example, 'setxkbmap dvorak it' will give you the American Dvorak layout, not the Italian one. They are faulty because, for example, 'setxkbmap dvorak ca' fails (because the rules expect the layout to be called "dvorak", not "fr-dvorak").

These rules may have been useful during a transition period of a few years, but now they are just anomalies that distract from the basic format of 'setxkbmap country-code variant-name'.

Additionally, the rule dvorak pl pl dvorak_quotes would never trigger because the earlier dvorak $dvoraklayouts %v dvorak rule would catch the 'dvorak pl' combo and give the user the plain 'pl(dvorak)' layout.
