rust: fix file folding map

The file folding map, frequently used on macOS, had two issues:

* the means for converting it to Python didn't work
* a minor typo when copying the python code, where `!=` became `==`

With this, the rust code passes all tests on macOS.

Test Plan:
I'm currently doing a full test run on a case-insensitive file system. If it passes, perhaps we can change the platform check from an error to a warning?
