tdf#119117: get phonebook sort work by tweaking ICU call mechanism

Using "phonebook" as variant does't work with de_DE
since it gives de_DE_PHONEBOOK whereas icu expects de__PHONEBOOK
See http://userguide.icu-project.org/locale#TOC-Variant-code,
   Level 2 canonicalization, 8.

So let variant empty and use the fourth arg of icuLocale "keywords"

See constructors in http://icu-project.org/apiref/icu4c/classicu_1_1Locale.html
