[processing][gdal] Ensure that GDAL algs output the CORRECT

generated filename for outputs

Previously they were just echoing the input parameter value,
which isn't always a string and accordingly was broken for
temporary outputs. This caused models to break when the output
of a GDAL algorithm was used in a subsequent model step.
