Saleh 097ef7ef91 plugin/file: run additional processing for CNAME/DNAME answers (#8337) ...

externalLookup, which resolves the chase for ordinary CNAME, wildcard
CNAME, and DNAME answers, returned a nil additional section. So a chased
SRV/MX/SVCB/HTTPS answer with an in-bailiwick target was missing the
target's A/AAAA glue, unlike the direct path.

Run additionalProcessing at externalLookup's return points so all three
callers add the glue, and add ordinary-CNAME, wildcard-CNAME, and DNAME
regression cases.

Fixes #6628
