This reverts commit 85a04fda1f.

Note:

This update is breaking iproute2 because of API changes, thus we have
to wait with the update until iproute2 is fixed to work with the new
API of xtables.

This reverts commit 2d84d999d1.

Note:

Long time there wasn't an official release and development itself seems
to be pretty dead.

Note:

This commit switches the upstream source of the pam_krb5 package to the
one provided by Redhat.
The formerly used sources were an old fork of that Redhat version of
pam_krb5 which seem to be not maintained anymore.

Note:

Most probably we can remove that package completely as it seems to be
obsoleted by lua-rings.
