Fix permission check for deleting  SMS on UICC.

When accessing SMS stored on UICC via TelephonyProvider, we need to
use the com.android.phone UID for the call to IccSmsInterfaceManager
to avoid a UID mismatch failure in the app ops check. Add code to
SmsProvider to save and restore the original caller identity.
