Alter thr_timer to allow server startup past 2038

Browse Source 
In previous commits, changes were made to use the entire 32 bit
unsigned range in order to support timestamps past 2038 on
64 bit systems. Without changing set_max_time on thr_timer to also
match this new range, the server will crash when attempting to
startup past 2038-01-19. Like the previous commits, this only
applies to 64 bit systems.
