util: numa: Stub out hugepage code on non-Linux platforms

Browse Source 
The hugepage sizing and counting code gathers the information from sysfs
and thus isn't portable. Stub it out for non-Linux so that we can report
a better error. This patch also avoids calling sysinfo() on Mingw where
it isn't supported.
