Tools: Use logical paths in ignored_dirs

### Description

Exporting to GNU ARM Eclipse, E2 Studio, and other exclude-based IDEs
currently generats unusable project files online. This is because the
list of directories ignored in the scan is inconsistant about what sort
of paths are used: logical paths, or phisical paths. This patch makes
all paths in ignored_dirs logical. This should fix the excluding tags
in these project files.
