wix: remove cacert.pem from Windows distribution It should not be included in the Windows installers because it prevents loading CA certificates from the system store on Python 2.7.9, implemented by 760a86865f80. The msi packages bundles Python 2.7.9, so cacert.pem is no longer necessary. Backed out changeset e5c2338d76b5
