[Xymon] Multiple Issues with 4.3.17 install

If you're seeing a crash alert ("Signal received", etc) and it's purple,
it was just the one-time note that something internal to xymon crashed.
(That, of course, isn't supposed to happen, but... :/ )

xymond_rrd normally doesn't send in a test about itself (none of the
processors launched via xymond_channel do by default, only the
xymonlaunch-ed daemons and run-once commands), so it won't clear even if
the system is running fine now.

Also, I'd have to check, but I believe re-enabling of disables doesn't
take effect right away -- there's a part that may not update until the
next status message is received for it.

In either case, just drop the now-spurious "xymond_rrd" test using
something like:

./xymon 0.0.0.0 "drop xymonems xymond_rrd"


HTH,
