Fix typo in Requirement#modify_build_environment: the PATH skip-list duplicated HOMEBREW_PREFIX/bin instead of including HOMEBREW_PREFIX/sbin.

[Copilot]

Pull request overview

Fixes a typo in Requirement#modify_build_environment so the PATH “skip list” correctly includes HOMEBREW_PREFIX/sbin (it previously duplicated HOMEBREW_PREFIX/bin), and adds tests to prevent regression.

Changes:

• Update Requirement#modify_build_environment to skip PATH prepends for both #{HOMEBREW_PREFIX}/bin and #{HOMEBREW_PREFIX}/sbin.
• Add RSpec coverage ensuring requirements that return a path under HOMEBREW_PREFIX/bin or HOMEBREW_PREFIX/sbin do not trigger ENV.prepend_path.
