Title: fix `cache_path: command not found` error

The following error occurred when `always_rebuild` is true.

```
Cleaning all cache to force rebuilds
/tmp/buildpack_xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/lib/misc_funcs.sh:
line 92: cache_path: command not found
```

And do not remove cache directory.
