Doesn't work with brewed python

[keith]

If vim / neovim is installed via brew, it uses python installed from brew, which fails to import lldb from Xcode 12. Example failure:

% /usr/local/Cellar/python@3.8/3.8.5/bin/python3
Python 3.8.5 (default, Aug 31 2020, 13:38:53)

According to the readme, it needs python 2 :(

It turns out the issue is lldb's macOS python support in general only supports the version shipped with Xcode https://lldb.llvm.org/resources/caveats.html#lldb-in-xcode-on-macos (or maybe at least only the version lldb was used to build with)
