Removing data hacks from ICU root.txt

Previously, the standard ICU data was modified
to support special short codes (e.g. PST, CET) in all
locales within SimpleDateFormat.parse().

This commit moves the modification into Java code
leaving the ICU data closer to upstream.

This change is associated with a change in libcore:
