skip conflicts resolved by file replacement
When replacing a file with a directory, any files inside the new
directory cannot possibly exist on the filesystem and can be skipped.
This allows cross-package symlink-to-directory transitions when there
are files with the same name under both the symlinked directory and the
new directory.
