    dnsmasq: fix remove pidfile on shutdown regression
    
    Regression introduced by 3481d0d dnsmasq: run as dedicated UID/GID
    
    dnsmasq is unable to remove its own pidfile as /var/run/dnsmasq is owned
    by root and now dnsmasq runs as dnsmasq:dnsmasq.  Change directory
    ownership to match.
    
    dnsmasq initially starts as root, creates the pidfile, then drops to
    requested non-root user.  Until this fix dnsmasq had insufficient
    privilege to remove its own pidfile.
