[cups] Allow only black and white printing

[Helge Blischke]

A (tested) example of a job patch file to do this is:

---snip---
*JobPatchFile 1:"%
/_sys_setpagedevice /setpagedevice load def
<</ProcessColorModel /DeviceGray
   /Duplex false
 >>_sys_setpagedevice
/setpagedevice
{
         1 index/ProcessColorModel 2 copy known{undef}{pop pop}ifelse
         1 index/Duplex 2 copy known{undef}{pop pop}ifelse
         _sys_setpagedevice
}bind def
%
"
---snip---
This is to be inserted into the PPD near the beginning, where the  
basic capabilities
are described.
