The ktime_get_real_seconds() stub returns 0, causing deleted inodes
to have zero i_dtime. This causes fsck to complain about deleted
inodes with zero deletion time.

Instead, use the boot-relative time in seconds. While not a real
wall-clock timestamp, it provides a non-zero value that satisfies
filesystem-consistency checks.

Future work can improve on this, perhaps using an on-board RTC.
