Fix reMarkable crash bug v2022.05: event overwrite with new time module (#9121)

The change from timeval to time completely broke reMarkable.
frontend/device/remarkable/device.lua was using TimeVal:now() to manually overwrite event time values, as noted in the code comments.
Input:handleTouchEv is expecting those event time values to be timevals, not integer times.
So as soon as the user touches the screen, crash.
