Android patch: Fix production data path in icu4c/source/data/build.xml

This CL fixes an issue which prevents usage of production data by the
ICU's build scripts. Those scripts expect to find proddata under
cldr-staging folder but this build.xml file for some reason attempts to
find it in cldr-aux. This CL should probably be upstreamed.

Test: ./tools/updatecldrdata.py
