GLIBC 2.23 Update Translations

[Adhemerval Zanella]

Hi all,

Due an overlook in the wiki release from my part I created the release tag
without updating both libc.pot and the translation po.  So I am aiming the
correct translation update to 2.23.1.  I also updated both on master and
already backported on the 2.23 branch.

The question is: are there enough changes to warrant a 2.23.1 with 
translation updates so people can use those tarballs?
