Use C11 alignas instead of pg_attribute_aligned

Replace pg_attribute_aligned with C11 alignas, for consistency with
current conventions.

(These new uses were added by commit fbc57f2bc2e, which was developed
concurrently with the switch from pg_attribute_aligned to C11 standard
alignas, and it ended up being committed with the "old" style.)
