This returns the device path as a list of joinable path components,

rooted at $EXTERNAL_STORAGE.
e.g., given

this would return

This handles a couple classes of paths differently than it otherwise would:
- All .pak files get mapped to top-level paks/
- Anything in the output directory gets mapped relative to the output
directory rather than the source directory.
e.g. given
'$CHROMIUM_SRC/out/Release/icu_fake_dir/icudtl.dat'
this would return
[None, 'icu_fake_dir', 'icudtl.dat']

host_path: The absolute path to the host file.
