    media-keys: Disallow screenshots when locked
    
    Allowing random people to create files in the user's home folder
    while the screen is locked is unexpected at best, so block the
    corresponding shortcuts (while still allowing taking screenshots
    to the clipboard for bug reports/reviews etc.).
    While at it, adjust the shortcut for screencasts as well (though
    the change their is purely informational, as screencasts are already
    blocked by the shell while locked).
