IMPALA-5077: add NUMA and current cpu to CpuInfo

NUMA information is found using the /sys filesystem.

The current CPU can be found using sched_getcpu(), which is supported
on all recent Linux kernels (unfortunately CentOS 5 shipped with an
older kernel, so we need a fallback).

Testing:
Confirmed that this built on a range of different Linux distros,
including CentOS 5, which is missing support for features like
sched_getcpu().
