Correct translation of Mac JIS Eisu & Kana keys

Browse Source 
Since UCKeyTranslate() converts these keys to Space key unexpectedly,
applications can't distinguish these keys by keysyms.
To solve it, this fix translates these keys by the same way with
function keys & keypad keys.
This patch is equivalent to the patch proposed in:
https://bugzilla.gnome.org/show_bug.cgi?id=702841

Closes #4117
