obmc-flash-bmc: Add ExecStartPre and Post to update environment variables
Backup the environment variables before performing an update.
Update the environment variables that point to the new volumes only
if all the ExecStart commands are successful. Also ensure that the
volumes exist so that the env variables point to an existing volume.
