Eddie Hebert d06f35623a MAINT: Make walk usage in example tests compatible with Python 3
The rename of walk is not provided by six, so check the import error
via an exception.

Also, callback behavior slightly changes between the two versions,
so instead iterate over the walked files and call what was formerly
a callback, directly as a function.
