Update git submodules

* Update helpcontent2 from branch 'libreoffice-6-1'
  - tdf#118571 avoid MSI problems with double / in Package_html*.mk
    
    MSI helpfully converts "help//fuse.js" into "help/help/fuse.js",
    which isn't obvious.  Or helpful, for that matter.
    
    Actually it might be the Perl installer code that messes it up,
    can't quickly check whose fault it is...
