mudp.c, multi.c, multi_io.c: get rid of 'all three DCO platforms' #ifdefs

With commit b66b80b2a all three platforms with DCO support have DCO float
notifications now, so the #ifdef inside multi_process_incoming_dco() is
no longer needed.

Also, the whole notification block (process_incoming_del_peer() and
multi_process_incoming_dco()) was surrounded by an

  #ifdef ENABLE_DCO "and all 3 platforms"

which is also not making sense anymore (if we add a fourth DCO platform,
we need to aim for having "all notifications from day 1", at least having
the stubs and defines).

Last not least, the event stuff in mudp.c and multi_io.c had grown the
same construct - and we'll need events for any future DCO platform, too.

So, fix those #ifdef as well, while at it.
