QPlatformPrintDevice - Add CUPS implementation

Add support to the CUPS print plugin for the new QPlatformPrintDevice
class.  Note this is called QPpdPrintDevicePrivate as it uses the CUPS
PPD support which is deprecated from CUPS 1.6 onwards.  A different
plugin will be implemented for the CUPS 1.6 support.
