Subject: [PATCH] plamo: Delete unnecessary process during container shutdown

Since some remounts/umounts is executed in the plamo shutdown script,
the filesystem on where a container exists might be mount as
read-only. This patch delete some mounts and umounts from the shutdown
script. It also delete hwclock setting process.

And delete an unncecessary output.
