build.sh: make /usr permission changes smarter

Browse Source 
If we only change the permissions on the directories then we won't
balloon the size of the container so much. As an example after the
changes in 17b3f5204, f7ef7d325 we ended up almost doubling the size
of the container:

```
builder@coreos-ppc64le-builder:~$ podman images
REPOSITORY                                 TAG              IMAGE ID      CREATED         SIZE
quay.io/coreos-assembler/staging           ppc64le-f7ef7d3  5ca4b8d1eae4  38 hours ago    9.18 GB
quay.io/coreos-assembler/staging           ppc64le-d34ab4a  659d6f7bbf7a  45 hours ago    5.11 GB
quay.io/coreos-assembler/staging           ppc64le-17b3f52  d2e55354e43f  2 days ago      5.11 GB
```

This should make it so the duplicated files in layers are only
directories so they take up much less space.
