Fix platform checks in Clipboard.

Fix platform checks in Clipboard.

Ozone uses clipboard_aura and DChecks in WriteObjects with type
CLIPBOARD_TYPE_SELECTION fail here as this is defined only for X11 
platform. This CL replaces the current platform checks(X11) with 
checks this shouldn't be defined on.

This is causing DCHECK failure when using Chromium with Aura + Ozone. I am not
familiar with this part of code.

Hm...

Perhaps it'd be clearer to just say what platforms this shouldn't be defined on:
!defined(OS_WIN) && !defined(OS_MAC) && !defined(OS_CHROMEOS)?
