[libcxx] Mark do_open, do_get and do_close parameters unused when catopen is missing
When catopen is missing, do_open, do_get and do_close end up being no-op, and as such their parameters will be unused which triggers a warning/error when building with -Wunused-parameter. Differential Revision: https://reviews.llvm.org/D56023
