This fix is only needed if #10635 was backported but it doesn't seem the case.

…ddress` precompiles (#10861)

I couldn't see where the weight is charged in those builtin pre-compiles
and a quick test indicated that there's no charges implemented. Assuming
those are compute-heavy functions, the missing weight charges seem like
a serious DoS vector.
