    build.7: Improve make delete-old example
    
    Be more explicit that deleting old files and libraries needs to be
    really after you're rebooted a third time and you're really actually
    sure your applications aren't using old libs, following irc discussion.
    
    Also adjust an example slightly to fit on 80 character console.
    
    MFC after:              3 days
    Discussed with:         emaste, fuz, jhb
    Differential Revision:  https://reviews.freebsd.org/D54079
    
    (cherry picked from commit 1d69c8e4ac7da648f63a830b23b872582469ba37)
