AFAIK, this is the default location where Homebrew (https://brew.sh/)
puts binaries, at least on new installations.  (The Homebrew directory
structure has changed slightly over the years, but I don't know if this
is one of them since I only noticed it those changes passing.)

I think it might make sense to add it to `tramp-remote-path`, but I'm
not familiar enough with Tramp to understand all the implications of
doing so.  I'm copying in Mattias and Gerd, who I believe are using
macOS, in case they have anything to add.
