duplicity: Fix installation with distutils.cfg

The Homebrew Python installations place a `distutils.cfg` file that can override
arguments passed on the command line. Specifically, our `distutils.cfg` sets a
value for `install-lib`, so `--install-lib` needs to be passed to `setup.py` to
override this default. Passing `--install-purelib` and `--install-platlib` is
not sufficient.

mit-scheme: fix hardcoded SDK paths in patch

This formula was failing to build for me with the following error:

    configure: error: No MacOSX SDK for version: 10.8

Traced problem to hard-coded paths to the SDKs used when patching
`src/configure` and `src/lib/include/configure`.  Replaced
hard-coded paths with calls to `xcode-select --print-path`.

Closes #16166.

doctor: don't check keg-onlies if cellar doesn't exist
Don't print error message when dev_tools_path fails to find tools

This message is either (a) never printed because the tools are
installed, or (b) printed every time this method is called.

See #16119.

This code shouldn't be responsible for UX anyway, so just remove it and
let other parts of Homebrew be responsible for failing or declaring that
they need the developer tools.
