Update German AM/PM marker to the previous value

In CLDR 32.0 (used in ICU 60), German AM/PM markers were changed to
'AM' and 'PM', but the change is controversial. For now, revert to
the previous values per the upstream (CLDR 32.0.1 / ICU 60.2). See
   https://unicode.org/cldr/trac/ticket/10735 .
