time: Use ktime_get_real_seconds() in time syscall



Both get_seconds() and do_gettimeofday() are deprecated. Change the time()
implementation to use the replacement function instead.

Obviously the system call will still overflow in 2038, but this gets us
closer to removing the old helper functions.
