  -----------
  [libc++] Remove sysctl-based implementation of thread::hardware_concurrency()

Using sysctl requires including headers that are considered internal on
Linux, like <sys/sysctl.h> & friends. Instead, sysconf is defined by POSIX
(and we have a fallback for Windows), so all the systems we support should
be happy with just sysconf.
