[Xymon] Patch: ntpdate option -p deprecated

[Brian Scott]

The -p 1 option is still desirable for standard ntpd. The default is to 
do 4 probes which is overkill for xymon.

I have just checked a fresh install of ntpsec from source and can't see 
ntpdate being installed. Found this on the ntpsec site under Security 
Improvements:

  * The deprecated and vulnerability-prone ntpdate program has been
    replaced with a shell wrapper around ntpdig. Its -e and -p options
    are not implemented. It is no longer documented, but can be found in
    the attic/ directory of the source distribution.

I notice that in the script the behaviour when it finds the -p option is 
to simply warn and ignore it:

p) echo "ntpdate: -p is no longer supported." >&2;;

So it's just a neatness thing. The script is undocumented (debian may 
have pinched their man page from standard ntp) and unlikely to ever be 
updated.

Not sure where this leaves us. I know others had similar problems when 
distros moved to chrony for ntp. Maybe we need a more generalised 
approach to different ntp implementations going forward.

Cheers,

Brian Scott
