Snapcraft runs a collision detection algorithm when attempting to merge two parts. This algorithm has two related issues:

1. It only compares files, which means files (e.g. symlinks) that collide with directories are missed.
2. If a file in both parts is a symlink, it immediately assumes they don't collide, without checking where they're pointing. If they point to different places they _should_ collide.
