cmake, cmake-devel: /opt/homebrew is in the default system path

[ryandesign (Ryan Carsten Schmidt)]

On Apple Silicon systems, Homebrew apparently installs into /opt/homebrew, and cmake knows this and adds that path to the system path on Apple Silicon systems. This resulted in a build failure of Aseprite when the user also had Homebrew installed. See #64103. I think we should patch the cmake port so that it does not search this path. We already patch cmake so that it does not search the Fink path /sw.

I think this also caused #68254.

In 4c0ec16c0bace1d91e3cb243b363cd90c6cf1fac/macports-ports (master):

cmake-devel: remove homebrewisms (​https://github.com/macports/macports-ports/pull/20758)

• There are some hardcoded references to homebrew paths, that have crept into cmake over time. Remove these.
• Prevents homebrew-installed software like python from being detected over the settings in PATH and PREFIX, if the user happens to have homebrew installed in /opt/homebrew

See: #64111
