Arabic scripts: More fixes after the recent import.

After the recent import of month names from CLDRv31 (bug 21217,
commit c853f14) more imports are also needed, mostly abbreviated month
names.

This patch also updates May (full month name) in ps_AF which was
skipped in the previous patch.

Incidentally, this import fixes bug 17225 (ar_SY) and partially
bug 19066 (ar_SA).

CLDR currently has a bug in the full month name for October for ar_IQ, see
http://unicode.org/cldr/trac/ticket/10460
