tools/makemanifest.py: Support freezing a subdirectory recursively. 

This adds support for freezing an entire directory while keeping the
directory as part of the import path.  For example

    freeze("path/to/library", "module")

will recursively freeze all scripts in "path/to/library/module" and have
them importable as "from module import ...".
