Fix OSX issue with snprintf wrapper macro

(bug introduced in commit 7bef74b)

OS X for some reason has problems with defining snprintf as a macro
and including another macro expansion in its arguments.

* cord/tests/cordtest.c (GC_SNPRINTF_BUFSZ_ARG): Remove.
* cord/tests/cordtest.c (GC_SNPRINTF): Do not define if no snprintf()
available.
* cord/tests/cordtest.c (test_printf): If GC_SNPRINTF undefined then
use sprintf() instead.
