arrow-cpp: fix TestAzuriteGeneric.Empty exclusion on x86_64-darwin

The test was in disabledTests, which feeds ctest --exclude-regex
and only matches ctest target names (e.g. "arrow-azurefs-test"),
not individual googletest cases. Moved it to GTEST_FILTER where
individual test names are actually filtered.
