SW: drop ifenslave from GRML_SMALL and GRML_FULL
Quoting /usr/share/doc/ifenslave/NEWS.Debian.gz:
| ifenslave (2.10) unstable; urgency=medium
|
| This version of the ifenslave package no longer provides /sbin/ifenslave. The
| /sbin/ip command from the iproute2 package supports creating bonding masters
| and enslaving other interfaces to it.

ifenslave is no longer in Debian/testing since 2021-09-14 due to RC
bugs, and therefore we don't have any recent Debian/testing based daily
ISOs anymore. Given that iproute2 supports network bonding, let's drop
ifenslave from our package list.
