docs: adjust sentece, fix minor typo

The verity partition types are per-architecture already, and they contain the
hash data independently of whether we are on a given architecture. (Or in other
words, we would make *use* this partition on some architecture, but the
contents always *exists*.)

If the partition is encrypted with LUKS, the device mapper file will be named `/dev/mapper/tmp`. Note that the intended mount point is indeed `/var/tmp/`, not `/tmp/`. The latter is typically maintained in memory via <tt>tmpfs</tt> and does not require a partition on disk. In some cases it might be desirable to make `/tmp/` persistent too, in which case it is recommended to make it a symlink or bind mount to `/var/tmp/`, thus not requiring its own partition type UUID. |
