[merge to m59]md settings: Fix dialog buttons on lock screen.

Fix the password prompt, pin setup, fingerprint setup dialogs on the lock screen. They dont use the 'button-container' class from cr-dialog, so they are missing some margins/paddings the other dialogs have. Also the previous 'button-strip' was part of the body content of cr-dialog.
