Move all translation into the main locale directory.

This is for consistency reason as the lib/dtutils/file.lua use this
directory. Also all translation into contrib where not usable as
not checked into this directory which was expected to be just lua.

All in all using locale directory will avoid clutter the main
directory with all possible languages and fixes the current scripts.
