Workaround bad Window error in clipboard code

[Dominik Strasser]

Without the patch below I get BadWindow X11 errors if something is
selected on the X11 side.
This happens at least in MS Word 97.

Changelog:

* windows/x11drv/clipboard.c:
	Dominik Strasser <dominik.strasser at t-online.de>
	Workaround X11 BadWindow error if no parent window is found
