Fix failure to detect some cases of improperly-nested aggregates.
check_agg_arguments_walker() supposed that it needn't descend into
the arguments of a lower-level aggregate function, but this is
just wrong in the presence of multiple levels of sub-select. The
oversight would lead to executor failures on queries that should
be rejected. (Prior to v11, they actually were rejected, thanks
to a "redundant" execution-time check.)
Per bug #17835 from Anban Company. Back-patch to all supported
branches.
