Rename locale.{c,h} to iperf_locale.{c,h} to avoid filename collision

with system header <locale.h>.

This apparently fixes problems on an ARM build, but this was generally
broken anyway.  It's slightly amazing this didn't cause problems before;
perhaps we never used <locale.h> before?

Addresses #203.
