Works around a flaw in the upgrade logic of the system contracts. Since
they are updated directly, without first being self-destructed and then
re-created, the usual incarnation logic does not get activated, and all
historical records of the code of these contracts are retrieved as the
most recent version. This problem will not exist in erigon3, but until
then, a workaround will be used to access code of such contracts through
a special structure, `SystemContractCodeLookup`
