knot-resolver: update DNSSEC root trust anchors

This is long overdue.  Honestly I dislike that packaging
is hardcoding it this way.  It's error-prone, as we can see.
Knot Resolver source does contain the up to date anchors,
and it also (optionally) installs them.  Still, I'm not up to
larger changes in OpenWrt packaging right now.
