veristat: Document verifier log dumping capability

Browse source

`-vl2` is a useful combination of flags to dump the entire
verification log. This is helpful when making changes to the verifier,
as you can see what it thinks program one instruction at a time.

This was more or less a hidden feature before. Document it so others can
discover it.
