Bug: Yarn workspace foreach do not exit when sub-process fails

[akphi]

This is a reproduction of issue mentioned in yarnpkg/berry#2486

Each workspace has a script called doSomething. pkg1 will exit with code 1 since the command error is not known.

At the root directory, if we run the following command, we got some unexpected result:

yarn workspaces foreach run doSomething                                          # no error
yarn workspaces foreach --all run doSomething                                    # no error
yarn workspaces foreach --parallel run doSomething                               # no error
yarn workspaces foreach --all --parallel --topological-dev run doSomething       # error
