In #188049 we missed some test failures because GitHub CI does not have
libxml2 installed. I checked the logs and found a couple of other things
missing.
In this change I'm adding to the Linux container:
* libedit
* libxml2
* liblzma
I am not adding ncurses because this would enable text user interface
tests that are often unstable. They do run post-commit, and don't change
that often anyway.
I am not adding Lua or TreeSitter because they are more obscure and are
tested somewhere post-commit (in Green Dragon I think).
