filepath.Clean shows up in profiles as a hot spot, and there seem to be
many redundant calls, particularly in ignorelist handling. We can avoid
these redundant calls by pre-cleaning entries in the ignore list, and
providing fast paths when we know we're already dealing with a cleaned
candidate path.

* fix: Correct flatten function in layers
- Added a test.
- Cache current image, track deletes in `whiteouts` as well as normal adds in `layers`.
- Fix ugly delete behavior of `layerHashCache`.
Delete it when crerating a new snapshot.
- Slight cleanup in `snapshot.go`.
- Format ugly `WalkFS` function.
* fix: Add symbolic link changes to Hasher and CacheHasher
* fix: Better log messages
* fix(ci): Integration tests
* fix(ci): Add `--no-cache` to docker builds
* fix(ci): Pass credentials for error integration test
* np: Missing .gitignore in `hack`
* np: Capitalize every log message
- Correct some linting.
* fix: Key function
- Merge only last layer onto `currentImage`.
* fix: Remove old obsolete `cacheHasher`
The directory created by `T.TempDir` is automatically removed when the
test and all its subtests complete.
