Pull in tableoid for inheiritance with rowMarks 

As noted by Etsuro Fujita [1] and Dean Rasheed[2],
cb1ca4d8 changed ExecBuildAuxRowMark()
to always look for the tableoid in the target list, but didn't also
change preprocess_targetlist() to always include the tableoid.  This
resulted in errors with soon-to-be-added RLS with inheritance tests,
and errors when using inheritance with foreign tables.

Minor word-smithing on the comments by me.
