Late-model clang is able to notice, when building posix_sema.c with USE_NAMED_POSIX_SEMAPHORES not defined, that the static variable nextSemKey is set once and read nowhere. Rearrange the #ifdef's to not declare or set it unless USE_NAMED_POSIX_SEMAPHORES. As a small side benefit, we can skip a stat() call altogether if we're not going to need it to initialize this variable, which I think clarifies the code a fraction. Per buildfarm member fritillary.
