Remove Java 7 specific syntax from this local Android patch:

https://android.googlesource.com/platform/external/icu/+/02a8b1c

ICU4J is still built as Java 6, as specified here:

https://android.googlesource.com/platform/external/icu/+/dcdfae8/icu4j/main/shared/build/common.properties#23

Using Java 7 specific syntax in ICU4J code breaks the ICU4J build, used
for running the ICU4J test suite (ant check).

Test: ant check
