Subject: [PATCH] On Windows, add `lrand48` sources to Csmith compile.

When using CMake to build Csmith on Windows, compile and link with an
implementation of `lrand48`.

This commit also moves the relevant source files from `runtime/windows`
to `src/windows`.  Until now, we would distribute the source files but
not compile them or link them with Csmith.
