Switching to a selinux profile caused more USE flags to be enabled
(selinux, audit, caps), thus more dependencies to be pulled. More
dependencies caused two things:

- cyclic dependencies appeared
- sys-apps/baselayout is being pulled in

Cyclic dependencies need to be handled in a similar way it was done in
build_packages, thus factor out the code doing it into a separate and
reusable part.

The dependency on baselayout needs to be handled by installing the
package as a first thing in $ROOT, followed by a more careful way of
copying things from $SYSROOT to $ROOT (due to split-usr differences),
followed by installing the rest of the packages.
