[Xymon] No cpu utilization graph under openSUSE 13.1

[henrik at hswn.dk]

OK, got it now. The problem isn't with vmstat, it is with "top".

Xymon doesn't use the "top" output except to display on a status page. 
But the output from "top" in the client data message comes just before 
the "vmstat" output. And the output from "top" in OpenSuSE 13.1 has no 
final new-line ... so the client data ends up being garbled:

[top]
... lots of top output ...

Xymon expects that '[vmstat]' marker to be at the beginning of the 
line. When top doesn't terminate the final line, then it ends up as 
above and Xymon doesn't see it.

So the solution is simple: Change the xymonclient-linux.sh script that 
generates the client data. Near the end of the script is where 'top' 
runs, so add a blank line to the output right after top:

    if test -x "$TOP"
     then
         echo "[top]"
         $TOP -b -n 1
         # Some top's (OpenSUSE 13.1) do not output a final newline ...
         echo ""    <---- add this line
     fi
