src: remove nftnl_rule_cmp() and nftnl_expr_cmp()

These functions are not very useful, rule comparison from this layer
does not work well with implicit set definitions.

This infrastructure was added as an attempt to support for deletion by
name from this layer, which should be done from higher level libnftables
library. Finally, we never had a client for this code in
git.netfilter.org.

Let's remove it and bump libversion for safety reasons.
