[libvirt] [PATCH 2/2] nodeinfo: make freebsdNodeGetCPUCount work on Mac OS X

This fixes the following error: error : nodeGetInfo:933 : this function is not supported by the connection driver: node info not implemented on this platform Mac OS X can use sysctlbyname as same as FreeBSD to get the CPU frequency. However, the MIB style name is different from FreeBSD's. And the unit of the return frequency is also different.
