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.
