Change custom data type from map to unordered_map in preperation for mojofication.

clipboard_messages currently defines a CustomDataMap as:

typedef std::map<base::string16, base::string16> CustomDataMap;

When this moves to mojo is will become an unordered_map - this work is to make this
change now so we can make sure it doesn't introduce and side effects.
