Drop support for building with ghc older than 8.4.4, and with older versions of serveral haskell libraries than will be included in Debian 10. The only remaining version ifdefs in the entire code base are now a couple for aws! This commit should only be merged after the Debian 10 release. And perhaps it will need to wait longer than that; it would make backporting new versions of git-annex to Debian 9 (stretch) which has been actively happening as recently as this year. This commit was sponsored by Ilya Shlyakhter.
