[PATCH v2 1/2] f2fs: Show casefolding support only when supported

[Daniel Rosenberg]

The casefolding feature is only supported when CONFIG_UNICODE is set.
This modifies the feature list f2fs presents under sysfs accordingly.

Fixes: 5aba54302a46 ("f2fs: include charset encoding information in the superblock")
