      Bug#54467 performance schema complains of wrong structure in bootstrap mode
      Prior to this fix, the installation script:
      - did print [Note] messages in the server log,
        related to the performance schema.
      - did print [ERROR] messages in the server log,
        complaining about performance schema tables.
        These errors are not justified during bootstrap.
      With this fix:
      - notes are no longer printed,
        this reduces the server verbosity.
      - integrity checks for the performance schema tables
        are not performed when tables are not expected to be there,
        to avoid un justified [ERROR] messages.
      Tested the mysql_install_db script manually:
      Installing MySQL system tables...
      Filling help tables...
