rpm: fix for SUSE build and %BASE_VERSION macro

See merge request !1267

This should prevent SUSE build from complaining:

    directories not owned by a package:
    - /usr/lib64/knot
    - /usr/lib64/knot/modules-3.1

rpm %() macro requires double escaping

nameserver: allow applying one DNAME repeatedly (e.g. DNAME loop)

Closes #714

See merge request !1243

The reason for this change is to reduce possible amplification attacks and
other negative effects of long processing loops.

Also most resolvers don't accept multiple jumps without requerying, so this
change should be harmless.

This seems to be supported in Debian unstable only.
