[PATCH openbmc 05/16] initfs: update: Do not cause an error if no files were saved

[OpenBMC Patches]

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

If there were no files in the read-write overlay file system that
were in the persistent file list, then the save directory will
not be created and therefore not exist.  Skip attempting copying
the non-existent directory in that case to avoid the error message.
