stub out injectTime API as we should not handle that

 -CR#2595204: We should no longer accept the NTP injection from AFW
  as we have our XC handling the NTP update.

 -CR#2605697: HIDL API impl can not return false, else it would fail
  VTS.

Bug: 147337616

Test: Wake up device 1 hour after first NTP time_inject and start GPS
