Fix the failed case ValueStoreTest.DotsInKeyNamesWithDicts for Android
Json parser uses a stack-based input copy string and the parsed result
'Value' references the internal pointer of the input copy string. To
make the references valid, 'Value' has one member std::string to swap
its content with the input copy string. On other platforms, the member
std::string can get the internal pointer of the input copy string.
However, on Android, std::string just swaps the content of two strings
instead of swapping their internal pointers. This makes the pointer
reference of value invalid.
Fix this by forcing options |= JSON_DETACHABLE_CHILDREN for Android so
disable this optimization.
