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.
