Modified Files:
        src/sys/arch/virt68k/dev: gfrtc_mainbus.c
        src/sys/dev/goldfish: gfrtc.c

Log Message:
Fix two problems that the time runs late on virt68k.
- The time between the time the alarm occurred and the time read by
  TIME_* register in the next interrupt handler was not accumulated.
- With the one-shot timer method, once the host time prolongs, the
  guest time will never be able to catch up with the host time again.
New one does:
- The driver maintains its (guest's) time (as sc_alarm_time) and always
  set the next alarm sc_interval_ns after the previous alarm.
- gfrtc_set_alarm() takes an absolute time instead of a relative time
  as the argument.
PR kern/57980.  Confirmed on QEMU.
