Fix invalid prototype for tcase_name(void)

The existing prototype in check.h is `const char* tcase_name()`. This
causes issues on platforms that use strict prototype checking, e.g. the
latest clang compiler with -Wstrict-prototypes ('this function
declaration is not a prototype [-Werror,-Wstrict-prototypes]').
