Send LOCKED_BOOT_COMPLETED on same queue as BOOT_COMPLETED

Make sure that the LOCKED_BOOT_COMPLETED broadcast is dispatched via the
same delivery queue as BOOT_COMPLETED.  Currently, it's possible for an
app to receive the two broadcasts in reverse order, which violates the
start sequence contract.
