Restructure the tree a little to provide a module example.

I've written up how to build web.go here:

  https://sites.google.com/site/fullycapable/building-go-programs-that-manipulate-capabilities

But it struc me that the code itself does not explain about the
CGO_LDFLAGS_ALLOW workaround, so I've relocated the web.go code
and included a README as well as a pointer to the above explanation.
