[PATCH 6/6] setup: Add dependencies for Windows

[Simon Glass <sjg@chromium.org>]

From: Gua Guo <gua.guo@intel.com>

Windows apparently builds pylibfdt if swig is declared as a dependency
in the setup file. Otherwise it must be installed manually and Windows
does not sport a package manager, so this is hard for users.

This change seems to have no ill effects on Linux, at least.

So add a new setup_requires line.
