Ian Romanick c12b52b856 util: Set util_cpu_caps.num_cpu_mask_bits based on total CPUs in the system 
In the current code, this prevents a very unlikely corner case.  More
importantly, it should prevent the next commit from breaking the
universe.

Imagine a system with 64 CPUs configured, but first 32 CPUs are offline.
_SC_NPROCESSORS_CONF will return 32.  All of the surrounding code will
interpret this as meaning CPUs 0 through 31, but all of those CPUs are
offline.  Nothing good can happen then.

The problem cases require systems with more than 32 CPUs because
util_cpu_caps.num_cpu_mask_bits is always rounded up to a multiple of
32.
