Subject: [PATCH] Fixed a SIM Lock UI issue

+ The SIM lock option will now appear if there is any SIM with locking
capabilities.
+ Also, if the first slot does not have a SIM in it, then the SIM lock
screen will disable the ability to lock the first slot.

Bug: 18473536
Change-Id: Ib4e0ed6e94b00bc07c9febdad433fdb3c55294b8
