[PATCH openbmc v2 13/34] update: Make cow directory before restoring saved files.

[OpenBMC Patches]

From: "Milton D. Miller II" <miltonm at us.ibm.com>

This will ensure the cp command always writes to an existing
directory but will also make any future component directories if
the upper directory is later moved from the root of the filesystem.
