Depends on https://codereview.chromium.org/254673004/ which
introduces new layout manager for LockScreenContainer.

This means that lock screen UI now supports resizing when virtual
keyboard is shown and overscroll is disabled. Custom code for
lock screen that "scrolled" user pods into view is not needed anymore,
reusing login UI solution (http://crbug.com/363635).

This CL partially reverts https://codereview.chromium.org/304153004

To disable lock screen scroll into view use same --disable-login-scroll-into-view
