[PATCH 0/2][BZ 21217] Update months from CLDR-31

[Rafal Luzynski]

While working on another glibc bug (10871 - months in genitive case)
I processed months in all locales and I noticed that about 50
of them probably need to be updated.  I don't want to waste
the work I already did so I filed a bug report [1] and here
I post two patches.  I'm not sure they are correct but also it
may happen they are correct and some local communities will
profit from them.

The patches contain only 22 locales.  I will add more to bugzilla
later.

Also I've set up a copr repository [2] which contains these
patches already applied so those who use Fedora can test it
already.

Best regards,

Rafal
