Configure repository.directory for monorepo packages

This is the standard configuration value for deep-linking into a
package's directory within a monorepo.

npm RFC: https://github.com/npm/rfcs/blob/latest/implemented/0010-monorepo-subdirectory-declaration.md

This will ensure the packages' pages on npmjs.org will link to the
correct directory.

Also, _eventually_, it will ensure the `npm repo` command opens to the
correct location: npm/cli#163

Lastly, this is _required_ for monorepo packages to be successfully
published to the GitHub Package Registry (if that is ever considered in
the future).
