cua: quiet warning messages

[Michael Mauger]

I've noticed that when CUA starts up under 21.3.50 that it issues warning
messages when delete-selection-mode and pc-selection-mode are disabled. 
Actually the error is issued by the modes themselves.  The warnings are:

Toggling delete-selection-mode off; better pass an explicit argument.
Toggling pc-selection-mode off; better pass an explicit argument.

This patch corrects this by passing the explicit argument.
