thread-utils.c: detect CPU count on older BSD-like systems

Not all systems support using sysconf to detect the number
of available CPU cores.  Older BSD and BSD-derived systems
only provide the information via the sysctl function.

If HAVE_BSD_SYSCTL is defined attempt to retrieve the number
of available CPU cores using the sysctl function.

If HAVE_BSD_SYSCTL is not defined or the sysctl function
fails, we still attempt to get the information via sysconf.
