tests: shell negation portability fix

Commit 969c8775 introduced a test which uses the non-portable construct:

  command1 && ! command2 | command3

which must be

  command1 && ! (command2 | command3)

to work on bsd shells (this is another example of bbf08124, which fixed
several similar cases).
