tools: improve update-eslint.sh

* Pin version numbers when using `npx`. This means we can be careful about updating what we run. (Thinking about the recent eslint-scope thing.) * Add removeNPMAbsolutePaths to get rid of unused fields in package.json files. These unused fields can cause unnecessary churn, as at least one contains an absolute path that will be different for each developer.
