Use contents directory on Atmosphère >= 0.10.0

[TheLastZombie]

Starting with Atmosphère 0.10.0, titles has been renamed to contents, essentially leaving the KIP list blank.

See https://github.com/Atmosphere-NX/Atmosphere/releases/tag/0.10.0:

• Atmosphere's process override layout was changed.
  • Atmosphere now uses the /atmosphere/contents directory, instead of /atmosphere/titles.
    • This goes along with a refactoring to remove all reference to "title id" from code, as Nintendo does not use the term.
  • To make this transition easier, a temporary functionality has been added that migrates folders to the new directory.
    • When booting into 0.10.0, Atmosphere will rename /atmosphere/titles/<program id> to /atmosphere/contents/<program id>.
      • This functionality may or may not be removed in some future update.
    • This should solve any transition difficulties for the typical user.
    • Please make sure that any future mods you install extract to the correct directory.
