Thomas Huth ae84c738e4 system/rtc: Fix a possible year-2038 integer overflow problem
rtc_realtime_clock_offset is initialized with:

  rtc_realtime_clock_offset = qemu_clock_get_ms(QEMU_CLOCK_REALTIME) / 1000;

And QEMU_CLOCK_REALTIME might be based on gettimeofday() in certain
cases (see get_clock_realtime() in include/qemu/timer.h). So this
counter will exceed 32 bits in the year 2038, thus we should not
store this value in a normal integer variable. Change it to a time_t
to fix the problem.
And while we're at it, also adjust the nearby rtc_host_datetime_offset
variable to be on the safe side in the related code.
