When the guest is built using dracut and the agent uses glibc (esp. ppc64le/s390x), libraries might be missing. In my case, it was `libutil.so`, but more can be added easily. Add a script to configure `install_items` for dracut w.r.t. `ldd` of the agent. Fixes: #2384 Signed-off-by: Jakob Naucke <jakob.naucke@ibm.com>
