This is actually a bug/typo in older versions of meson. What is actually 
required (in some cases) is python3-distutils. See 
https://github.com/pgbackrest/pgbackrest/commit/e00e33b52. The purpose 
of this commit is to not hardcode the python bin.

However, this requirement is only for certain older (but not too old) 
versions of Debian/Ubuntu. Ubuntu 24.04, for instance, does not have 
this package and works fine without it. Of the Ubuntu versions only 
focal seems to require it. The only Debian version we currently have in 
CI, stretch, does not require it.

It's a bit of a mess, but looks like we need to install 
python3-distutils just for bullseye and focal as a build dependency. Is 
that possible?
