Adapt API filters for removal of monitor-aware SWT classes

The MonitorAwareRectangle and MonitorAwarePoint classes have been made
package-private by SWT[1]. Because Draw2D re-exports SWT, this is
considered a breakage in API, which would require a major version
increment.

This change suppresses those errors, as they are not relevant for
Draw2D.
