Subject: [PATCH 15/23] feat(qeth_rules): remove qeth handling consolidated in
 95znet

Dracut module 95znet handles a superset of qeth_rules as of the preceding
commit ("feat(znet): use zdev for consolidated device configuration").

The instmods list in installkernel() seemed to have been incomplete because
qeth needs one or both of qeth_l2 and qeth_l3 but qeth intentionally does
not depend on them so depmod cannot resolve that.

In contrast to the old dracut module 95znet, 95qeth_rules also did not seem
to have parsing for the upstream dracut cmdline options "rd.znet=" and
"rd.znet_ifname=".
