Fix memory alignment in pg_mcv_list serialization

Blind attempt at fixing ia64, hppa an sparc builds.

The serialized representation of MCV lists did not enforce proper memory
alignment for internal fields, resulting in deserialization issues on
platforms that are more sensitive to this (ia64, sparc and hppa).

This forces a catalog version bump, because the layout of serialized
pg_mcv_list changes.

Broken since 7300a699.
