• Fix usage of homebrew taps

    When installing autoconf213 from the homebrew/versions tap, salt
    correct installs the package but fails to verify its installation
    because it compares 'homebrew/versions/autoconf213', which is the
    specified package name, with 'autoconf213', which is the installed
    package name. Use the brew.install module function as a workaround
    until this functionality is added to pkg.installed or pkgrepo.
