remove i386ancient and need at least debian stable to build

* Removed the i386ancient standalone tarball build for linux, which
  was increasingly unable to support new git-annex features.
* Removed support for building with ghc older than 9.0.2,
  and with older versions of haskell libraries than are in current Debian
  stable.
* stack.yaml: Update to lts-23.2.

Note that i386ancient was targeting linux 2.6.32, which has been EOL for
over 9 years now. Any old system still using such a kernel is certainly highly
insecure. And I suspect i386ancient had its own insecurities due to haskell
libraries and C libraries not having been updated.
