Fixes breakage to ada-mode introduced in #200190.
ada-mode recently gained a Makefile [1] which is intended for compiling
it in the ELPA worktree. Building from the ELPA release tarball still
needs to be done via build.sh, so we need to overwrite buildPhase to
ignore the Makefile (previously it'd just do nothing).
Additionally some new build tools are needed and lzip can be removed (as
we no longer fetch an archived version of wisi from ELPA).

Currently, AOT native-comp for emacs packages is implemented[1] in
postInstall. These packages override postInstall and do not keep
old.postInstall, so they do not do AOT native-comp. This patch fixes
this by keeping the old.postInstall in their overrides.
Note that I do not fix emacspeak because I have not found an elegant
way to do so.

By upgrading the AdaCore libraries to their 22.*.* versions and GNAT to
version 11 we can finally upgrade wisi beyond 3.1.5 and probably
(hopefully) stay on latest for some time.
ada-mode includes extra binaries which are used by it at runtime. They
require gnat, gprbuild, gnatcoll-core and wisi's source checked out in
`../wisi-*`.
