Initialize InputMethodSubtype with "languageTag".

My previous commit [1] introduced a new XML attribute "languageTag" for
subtypes but forgot to initialize InputMethodSubtype object with that
attribute.  As a result, InputMethodSubtype#getLanguageTag() has always
returned null even if "languageTag" attribute is specified.

With this CL, InputMethodSubtype#getLanguageTag() starts returning the
value specified in the XML resource.
