In rewriteheap.c (used by VACUUM FULL and CLUSTER), calculate the tuple
length stored in the line pointer the same way it's calculated in the normal
heap_insert() codepath. As noted by Jeff Davis, the length stored by
raw_heap_insert() included padding but the one stored by the normal codepath
did not. While the mismatch seems to be harmless, inconsistency isn't good,
and the normal codepath has received a lot more testing over the years.
Backpatch to 8.3 where the heap rewrite code was introduced.
