dt-processor.sh: Add -O option to allow the user to add overrides

Additional MACHINEOVERRIDES can be automatically appeneded by using the
-O option.  No validation is preformed, but the value is used in the
generated content.  For example:

  dt-processor.sh .... -O override1:override2

The generated content will be:

  MACHINEOVERRDIES .= ":override1:override2"
