[PATCH] features: RUNDIR, imgdir, ... [update 1]

[Michal Soltys <soltys@xxxxxxxx>]

Make sure we actually mimic host's structure to not end with duplicate
files (harmless but wasteful) on hosts, where lib and lib64 point to the
same place.

We detect symlink/dir presence in the creation loop, so we don't have to
worry about $[usr]libdir.
