Cannot build selinux policy extensions from the bottlerocket main policy package

**What I expected to happen:**
I expected to be able to depend on the bottlerocket `selinux-policy` package to extend and add policies.

**What actually happened:**
Since `selinux-policy` installs `/etc/selinux` it conflicts with the `libsemanage` package that is already installed in the SDK.

```

**How to reproduce the problem:**
Try building a package that has a `BuildRequires` on `selinux-policy` and it will fail on conflicting file on `/etc/selinux`.

Reproduce the failure by building a package with a BuildRequires on selinux-policy in the Bottlerocket SDK. Inspect the selinux-policy and libsemanage package contents, then verify that the package can be installed without a /etc/selinux conflict and that the dependent policy extension builds successfully.
