Passing useLiveliness flag to FUL in startUi call

Because of changes in support of multi-user functionaity, the FUL
'eye blink' checkbox was no longer enabling liveliness detection.

It no longer makes sense to check the biometric flags (such as the
liveliness flag) inside of the Face Unlock service.  Instead, that
flag is now passed in from lockscreen via the aidl interface when
startUi is called.
