UBSan: Pack MACsec peer id structure

This is needed to avoid an UBSan warning and since this struct is used
as part of a message construction, it needs to be packed anyway to
guarantee correct functionality.

ieee802_1x_kay.c:1021:3: runtime error: member access within misaligned address 0x0000031921e2 for type 'struct ieee802_1x_mka_peer_id', which requires 4 byte alignment
