[PATCH] gdalwarp does not honour -s_srs with -cutline option

[etourigny]

When a cutline is used and source srs is not known (but set using -s_srs option), the following warning is given and source crs remains unknown.

Warning : the input vector layer has a SRS, but the source raster dataset does not.
Cutline results may be incorrect.

This simple patch resolves the issue by using the SRC_SRS value stored in papszTO.
