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.

Tested:
WVGA device while docked and opening/closing the keyboard.
