Remove configure probe for sys/resource.h and refactor.

<sys/resource.h> is in SUSv2 and is on all targeted Unix systems.  We
have a replacement for getrusage() on Windows, so let's just move its
declarations into src/include/port/win32/sys/resource.h so that we can
use a standard-looking #include.  Also remove an obsolete reference to
CLK_TCK.  Also rename src/port/getrusage.c to win32getrusage.c,
following the convention for Windows-only fallback code.
