Commit 6bcda4a721 replaced PG_DETOAST_DATUM with PG_DETOAST_DATUM_PACKED
in two BRIN output functions, for minmax-multi and bloom opclasses. But
this is incorrect - the code is accessing the data through structs that
already include a 4B header, so the detoast needs to match that. But the
PACKED macro may keep the 1B header, which means the struct fields will
point to incorrect data.
