bcachefs: Ensure that snapshot creation propagates has_case_insensitive



We normally can't create a new directory with the case-insensitive
option already set - except when we're creating a snapshot.

And if casefolding is enabled filesystem wide, we should still set it
even though not strictly required, for consistency.
