"Path" sanitization does not strip paths for native code

[mstange]

Profile: https://share.firefox.dev/3GitZfj

This profile contains filenames on C++ functions, for example /Users/mstange/code/mozilla/modules/zlib/src/deflate.c. This path has my username in it.

Steps to reproduce:

1. Click (Re-)Upload.
2. Check all checkboxes except "Include resource URLs and paths"

Expected results: The path with my username should not be part of the sanitized profile.

Actual results: The path is still there.
