Add missing include introduced due to new KConfig item

[atanisoft]

Unfortunately, the latest version (1.22.0) has a failure that is reported during builds:

In file included from .../managed_components/joltwallet__littlefs/src/littlefs/lfs_util.h:21,

This resolves the inclusion based on the new KConfig define.

thanks! released in v1.22.1 (currently being built in CI)

Thanks, I just happened upon it as part of testing this morning. Once 1.22.1 is out I'll switch it back over from SPIRAM only.
