[PATCH v3 15/16] fsck: reduce word legos to help i18n

[Nguyễn Thái Ngọc Duy <pclouds@xxxxxxxxx>]

These messages will be marked for translation later. Reduce word legos
and give translators almost full phrases. describe_object() is updated
so that it can be called from printf() twice.

While at there, remove \n from the strings to reduce a bit of work
from translators.
