compat with Endo on Yarn 4 (#9290)

refs: #451
refs: #9209 

## Description

We need agoric-sdk's integration tests to work with Endo running Yarn 4.
#9285 tested against
endojs/endo#2222. This PR is to land the
necessary changes in master so the Endo PR can land without breaking SDK
CI.

This helps with #9209 and is a subset of
#9286 , all that we need for
Endo right now.
