The subtype locale name on the spacebar will be suppressed when only
one subtype is enabled and
- Subtype locale is equal to the system locale.
or
- Subtype language is equal to the system language but the subtype is
implicitly enabled.
Thus the "es_ES" system locale chooses "es" subtype keyboard
implicitly but the keyboard doesn't have the subtype name on its
spacebar.
This change also removes Spanish Latin America keyboard.
