Keyguard layout was being skipped because the previous policy does not layout the status bar. This change lays out the status bar when it is serving as the keyguard. This change then allows the keyguard insets to be resized to make room for the IME when password security is selected. Fixes bug 14548156. Change-Id: Ice4f1072b463a22ec763a0cde69f342206bdd15a
