    bsdinstall: Install pkg if it's available
    
    Now that the pkg package is shipped on the pkgbase release media,
    install it by default for a pkgbase install if it's present.
    
    If it's not available (e.g., when running bsdinstall from a repository
    built from src alone, without ports), skip it and assume the user will
    install it another way.
