dhcp: refactor dhcp code to use @dhcp_anycast_addr as #GByteArray type

Browse Source 
At a later point, we will have to make a copy of @dhcp_anycast_addr to start
the client asynchronously. Although the length of the guint8 array *should*
always be 6 byte (being a MAC address), it's nicer to just pass on the
GByteArray instance instead, which knows how many byte are actually
set.
