erts: Fix erlang:monitor toward c-nodes

by suppressing DOP_MONITOR_P, DOP_MONITOR_P_EXIT and DOP_DEMONITOR_P
if not supported by the remote node.

In 17e198d6ee60f7dec9abfed272cf4226aea44535
I changed the behavior of erlang:monitor
to not raise badarg for c-nodes but instead create
a monitor to only supervise the connection.

But I forgot to prevent DOP_MONITOR_P and friends from being
sent to the node that does not expect them.

Note: We test both DFLAG_DIST_MONITOR and DFLAG_DIST_MONITOR_NAME
      for the node to support process monitoring. This is because
      erl_interface is buggy as it sets DFLAG_DIST_MONITOR without
      really supporting it.
ToDo: Should erl_interface stop setting DFLAG_DIST_MONITOR
      or should we change the meaning of these flags?
