Subject: [PATCH] feat: support patching during install

`python-build` supports a `-p` option to patch Python before installing. In
particular, I use this to apply a patch for OS X Big Sur before installing
older versions of Python.

I'm not super-wedded to this particular implementation: opening this PR for
more discussion.
