[stdlib] Disable legacy Unicode 8.0 regional break test.

Disables the portions of the regional break test file corresponding to
Unicode 8.0 vs 9.0 differences. Once the compiler and stdlib are in
sync with Unicode 9.0, and the legacy tries are dropped, we should
splat down newer versions of these test files.
