tmpfiles: when processing lines, always process prefixes before suffixes
If two lines refer to paths that are suffix and prefix of each other, then always process the prefix first, the suffix second. In all other cases strictly process rules in the order they appear in the files. This makes creating /var/run as symlink to /run a lot more fun, since it is automatically created first.
