org-plot: Ignore gnuplot buffer read-only error

Browse source 
* lisp/org-plot.el (org-plot/gnuplot): When
`gnuplot-send-buffer-to-gnuplot` is called, it may emit the error
"kill-region: Text is read-only: #<buffer *gnuplot*>" when the plot
operation has been successful.  This prevents `org-plot/gnuplot` from
executing the rest of the function, which is undesirable.
It's preferable just to ignore this error.
