Work around cross-version-upgrade issues created by commit 9e38c2bb5.

Summarily changing the STYPE of regression-test aggregates that
depend on array_append or array_cat is an issue for the buildfarm's
cross-version-upgrade tests, because those aggregates (as defined
in the back branches) now won't load into HEAD.  Although this seems
like only a minimal risk for genuine user-defined aggregates, we
need to do something for the buildfarm.  Hence, adjust the aggregate
definitions, in both HEAD and the back branches.
