Consider long system notification sound set by user

User can change the system notification sound from a simple tone to a
long music though it is not a major user scenario. It is better not to
play the notification sound when SIM Toolkit application launch a dialog
or activity for DISPLAY TEXT or GET INKEY/INPUT commands.

Bug: 128811547
Test: Confirmed that the sound is started only when the keyguard exists.
