    busybox: move passwd applet to /bin
    
    busybox currently installs passwd into /usr/bin which prevents its
    'full' shadow-utils variant from being installed.
    Move the passwd applet to /bin to avoid that collision.
    shadow also provides /usr/bin/login which doesn't collide with busybox
    as the busybox login applet is installed at /bin/login.
