plug-ins: Fix GIH export crash due to selection-modes 

Like ranks, the number of selection modes are defined by gihparams.dim.
However, we were unconditionally setting GimpProcedureConfig's
"selection-modes" parameter to the gihparams.selection array, which 
might have more elements than we had dimensions. This caused a crash.
This patch moves the selection-modes code into the check for
gihparams.dim > 0, and copies only the relevant values into a separate
array to set them.
