[PATCH openbmc 4/7] initfs: update: no error if no files to copy to ram

[OpenBMC Patches]

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

If the saved files directory is empty because there were no files in
the read-write overlay file system that were in the persistent file
list, then the save directory will not exist, so skip copying the
non-existant directory in that case.
