There are conflict of config files between kea and lib32-kea:

| Error: Transaction test error:
|  file /etc/kea/kea-ctrl-agent.conf conflicts between attempted installs of
     lib32-kea-1.7.10-r0.core2_32 and kea-1.7.10-r0.core2_64
|  file /etc/kea/kea-dhcp4.conf conflicts between attempted installs of
     lib32-kea-1.7.10-r0.core2_32 and kea-1.7.10-r0.core2_64

Because they are all commented out, replace the expanded libdir path with
'$libdir' in the config files to avoid conflict.
