amcheck: In verify_heapam, allows tuples with xmin 0.
Commit e88754a1965c0f40a723e6e46d670cacda9e19bd caused that case
to be reported as corruption, but Peter Geoghegan pointed out that
it can legitimately happen in the case of a speculative insertion
that aborts, so we'd better not flag it as corruption after all.
Back-patch to v14, like the commit that introduced the issue.
