[llvm] [GitHub] Install libedit, libxml2 and liblzma to be used in Linux LLDB builds (PR #209129)

[David Spickett via llvm-commits]

https://github.com/DavidSpickett created https://github.com/llvm/llvm-project/pull/209129

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).
