Subject: [PATCH] ZTS: Casenorm fix unicode interpretation

Use `printf` to properly interpret unicode characters.

Illumos uses a utility called `zlook` to allow additional flags to be
provided to readdir and lookup for testing.  This functionality could
be ported to Linux, but even without it several of the tests can be
enabled by instead using the standard `test` command.

Additional, work is required to enable the remaining test cases.
