* https://opensource.apple.com/tarballs/mDNSResponder/mDNSResponder-${PV}.tar.gz
  is just redirect to unsafe github archives which are regenerated from time to
  time.

* We do have src-uri-bad QA check which prevents to use github archives in SRC_URI
  since 2019:
  https://github.com/openembedded/openembedded-core/commit/21f84fcdd659544437fe393285c407e1e9432043
  but this cannot catch such redirects, see:

* The tarball was regenerated recently as discussed in:
  https://github.com/orgs/community/discussions/45830

* Use top-level directory in S to fix DEBUG_PREFIX_MAP usage
  like the version in master does, the only exception here is that
  there still was top-level Makefile (which fails to set VER with:
  Makefile:26: *** missing separator.  Stop.
  so use the simple one like newer version in master)
* it's already included in master as part of version upgrade in:
  https://github.com/openembedded/meta-openembedded/commit/ec96eb577bd518b89e2e7834bd569ba269df458f
