Make procedure OUT parameters work with JDBC

A follow-up to the recently added support for OUT parameters for 
procedures.  The JDBC driver sends OUT parameters with type void.  This 
makes sense when calling a function, so that the parameters are ignored 
in ParseFuncOrColumn().  For a procedure call we want to treat them as 
unknown.  This is of course a bit of a hack on top of another hack, but 
it's small and contained and gets the job done.
