[PATCH 08/12] initscripts: let populate-volatile.sh create the /tmp link

[<Qi.Chen@windriver.com>]

From: Chen Qi <Qi.Chen@windriver.com>

Previously, the /tmp link (/tmp -> /var/tmp) was created by the
bootmisc.sh script. So in case of a read-only rootfs, this symlink
would not be created correctly.

The populate-volatile.sh script is intended to handle all directories
and files related to volatile storage, so we should let it create
the /tmp link.

In addition, because of the improments of populate-volatile.sh, the data
loss problem of bug#3404 is also resolved by this patch.
