wix: autogenerate wxs file for library files

Currently, dist.wxs contains an enumeration of .pyd and .dll
files staged to dist/lib by py2exe.

Having a manual list of files is error prone, as things can
easily get out of sync (as the previous commit demonstrates).
This is especially an issue for TortoiseHG, which ships a
number of custom modules, which may pull in additional dependencies.

Let's prevent this problem from manifesting by dynamically
generating a .wxs file containing the .pyd and .dll files staged
by py2exe.
