Fix `github.com/ledgerwatch/interfaces` revision

[wojciech-sei]

Command

go list -modfile=./go.mod -m -json -mod=mod all

produces error:

go: github.com/ledgerwatch/[email protected]: invalid version: unknown revision 539b8171d9f0

It's because that commit does not exist in the repo anymore.

Our code does not depend on github.com/ledgerwatch/interfaces. It is required only because imported github.com/ledgerwatch/erigon-lib uses it for code generation here: https://github.com/ledgerwatch/erigon-lib/blob/main/tools.go
