Fix 2572446: Also watch keyboard changes in PIN/Password unlock. DO NOT MERGE

The PIN/Password unlock screen was monitoring orientation changes.
However, while docked, this isn't useful since orientation remains
fixed.  This change makes PasswordUnlockScreen also looks for
changes to config.hardKeyboardHidden.

WVGA device while docked and opening/closing the keyboard.
