blockchain: fix sync at v14 boundary
Miners with MLSAG txes which they'd already verified included
a couple in that block, but the consensus rules had changed
in the meantime, so that block is technically invalid and any
node which did not already have those two txes in their txpool
could not sync. Grandfather them in, since it has no effect in
practice.
