Fixes annoying pecl update issues & swoole build failures by using the prebuilt tap.
This also properly manages updates & enables the extensions via files in conf.d instead. Very clean.

This is unused, since we are using lua plugins now and also does not work anymore, because Homebrew follows PEP668, which discourages installing packages without the package manager or outside of a venv.
