This replaces usage of grub_get_rtc() with grub_get_time_ms() in a few places
throurough the code. Aside from the gained precision, it also permits that
functionality to work on Coreboot.

The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and
how) you may access your data; but nobody's threatening your freedom: we
still allow you to remove your data and not access it at all."

* kern/disk.c: Replace `<grub/machine/time.h>' with `<grub/time.h>'.
(grub_last_time): Change type to grub_uint64_t.
(grub_disk_open): Migrate code from to using grub_get_time_ms().
(grub_disk_close): Likewise.
* normal/menu.c: Replace `<grub/machine/time.h>' with `<grub/time.h>'.
(run_menu): Migrate code from to using grub_get_time_ms().
* util/misc.c (grub_get_time_ms): New function.
