Fix emission of domain events messages

Browse Source 
The code which updated the message length after writing the
payload wrote the updated length word in the wrong place since
the XDR object was given a buffer pointing to the start of the
header payload, rather than message start.

* daemon/remote.c: Fix updating of event message length so that
  we actually send the payload, not just the header
