[libcalamares] Split translatable timezone data

- Hide the one file from lupdate by giving it a weird suffix
 - Call lupdate a second time for the timezone translations
 - While here, adjust so that the options precede the directories
   they are supposed to affect

I don't want to give the translation teams 444 new strings all
at once (about 90% of which don't need translation).
