libc++: support NaCl when building thread.cpp

Summary: NaCl shouldn't include sysctl.h when trying to determine std:🧵:hardware_concurrency, it should instead use sysconf(_SC_NPROCESSORS_ONLN) through unistd.h. No test needs to be changed, since hardware_concurrency.pass.cpp already tests that std:🧵:hardware_concurrency > 0.

Test Plan: make check-libcxx
