Use HW_PHYSMEM instead of HW_USERMEM in get_total_system_memory_impl

The code checked for sysctl being available and HW_PHYSMEM being
defined, but HW_USERMEM was actually being used with sysctl instead
of HW_PHYSMEM.

The case for OpenBSD, etc. use HW_PHYSMEM64 (which is obviously a
64-bit variant of HW_PHYSMEM) and the case for OSX uses HW_MEMSIZE
(which appears to be a 64-bit variant of HW_PHYSMEM).
