build: Split up src into app/ and libpriv/

We currently have an internal-only library, but the sources for it are
in the same dir as the app.  For future work on a public shared
library, we'll need a clearer source structure.

Start by just renaming the app files into `src/app/`, and the internal
private library into `src/libpriv/`, with the appropriate
`Makefile.am` changes.

Closes: https://github.com/projectatomic/rpm-ostree/pull/123
