[PATCH] hfs{plus}: add deprecation warning

[Christian Brauner <brauner@kernel.org>]

Both the hfs and hfsplus filesystem have been orphaned since at least
2014, i.e., over 10 years. It's time to remove them from the kernel as
they're exhibiting more and more issues and no one is stepping up to
fixing them.
