bcachefs: Fix build when CONFIG_UNICODE=n

94426e4201fb, which added the killswitch for casefolding, accidentally
removed some of the ifdefs we need to avoid build errors.

It appears we need better build testing for different configurations, it
took two weeks for the robots to catch this one.

Fixes: 94426e4201fb ("bcachefs: opts.casefold_disabled")
