confd: drop deviation for /if:interfaces-state

Not the most obvious patch, but let me explain -- there will always be a
conflict betweem usability and "maintainability".  The ietf-interfaces
yang model already declares /interfaces-state as deprecated, so we don't
really need to add a deviation 'not-supported', for usability, however,
it may be useful since the deviation helps cut out that tree completely.

While working with ietf-routing and our companion models, I found that
since it relies on ietf-interfaces, it also breaks the reload/reimport
of infix-routing while developing extensions/changes:

  $ lint.sh -f tree ieee802-* iana-if-type@2023-01-26.yang \
            ietf-interfaces@2018-02-20.yang \
	    infix-interfaces@2024-01-15.yang \
	    ietf-routing@2018-03-13.yang \
	    ietf-ipv4-unicast-routing@2018-03-13.yang \
	    ietf-ospf@2022-10-19.yang \
	    infix-routing@2024-09-22.yang
  libyang err : Not found node "interfaces-state" in path. (Schema location "/ietf-routing:routing-state/interfaces/interface".)
  libyang err : Target of leafref "interface" cannot be referenced because it is disabled. (Schema location "/ietf-routing:routing-state/interfaces/interface".)
  YANGLINT[E]: Parsing schema module "ietf-routing@2018-03-13.yang" failed.

The only way to change/update models for a given build is to either, a)
surgically remove offending models from output/target/, then reinstall
all dependencies and hope it works better, or b) rebuild from distclean.
In most cases you end up with alternative b).
