Subject: [PATCH] gitlab-ci, build: add Aarch64 build in our universal
 installer.

This is in part a port of commit 6f921b27bb from gimp-2-10 branch, except that I
could not easily cherry-pick because too much had changed already in the master
branch.
There are also a bunch of additional changes in some other glue scripts.

Also some rules which were in the 2.10 branch don't apply to the main one, such
as Python being copied from the x86 binaries, since clang-aarch64 has Python3
(unlike Python2).
