Windows: Added APR include path to libprocess configuration.

Partially addresses MESOS-3447, as APR is a dependency of the SVN
facilities of Stout.

On Unix builds, APR is expected to have been installed on the system
prior to building Mesos (usually by a package manager). Since Windows
does not have a package manager or a reasonble way of automatically
discovering where a package is installed (aside from the registry), our
CMake build system takes it upon itself to manage these system
dependencies.  This means that on Windows, we need to configure the
build to look for the APR headers in our custom-downloaded APR
repository.  Currently, though, we are not doing this, so when we'll
hit a compile-time error if we try to build (e.g.) `svn.hpp`.

This commit will introduce the APR include paths as part of the build
against Stout. Since Stout is a header-only library, it is (right now)
incumbent on whoever is bundling Stout up to manage the third-party
dependencies of Stout. In our current implementation, libprocess manages
the APR dependency for Stout, hence, we put this logic in libprocess.
