batctl: Force packed placment of tt_change

Every data structure which is used to send data over the wire must be fixed in layout to prevent incompatibility between different architectures. Those incompatibilities could be generated by extra bytes between members and at the end of the structure.

tt_changes_fill_buffer and tt_len use that structure to copy the correct amount of data from an internal structure to the actual packet. We must ensure that this packet buffer only has data which can be interpreted by any architecture.
