Cast away a char pointer signedness warning.

The oggpack_* calls expect an unsigned char *, but the self-test
code for convenience uses string literals for some of the test
vectors. This generates a warning on gcc and clang, at least.

We silence the warning by casting the literals to (unsigned char *).
