__fish_anypython: do not automatically run python3 on macOS

Browse Source 
macOS ships with a stub `/usr/bin/python3` which by default opens a
dialog to install the command line tools. As we run `python3` initially
at launch, this causes the dialog to appear on first run of fish, if the
command line tools are not installed.

Fix this by detecting the case of `/usr/bin/python3` on Darwin without
the command line tools installed, and do not offer that as a viable
python.
