wix: package missing .dll and .pyd files dist.wxs is currently missing some .pyd and .dll files which are picked up and staged by py2exe. This means that the WiX installer is missing some Python extension modules and their dependencies which are referenced by Mercurial or a Python package distributed with it. This commit adds the missing files to the WiX installer. Differential Revision: https://phab.mercurial-scm.org/D6137
