Do not start fingerprint HAL if it is unstartable
Some users may face the situation that the fingerprint module is
damaged, in which case the user should be able to use device. But
now on HIDL HAL devices, setActiveGroup will thrown a NPE during
boot process.
If the HIDL daemon cannot be found, do not start HAL and complete
this operation directly.
