Subject: Recognize --head as an alias for --HEAD

Homebrew currently recognizes "--head" during the install process, but
rather than actually fetch HEAD it just nags the user to use the
correct option.	Since we recognize the spelling anyway, this just
promotes the lowercase version to an official alias.

Closes #26555.
