dual-image: Mount alt dirs
To support dual image in static layout, it needs to mount secondary's
rofs/rwfs.
Update obmc-flash-bmc tool to support mounting 'alt-xxx' directories in
/run/media/alt-xxx, and try to mount the alt-rofs, alt-rwfs before
xyz.openbmc_project.Software.BMC.Updater.service starts.
The ExecStart command is prepended with `-` so that it does not matter
if the mount fails, because the alt chip may be empty or contain invalid
data.
Tested: Verify the obmc-flash-bmc-static-mount-alt.service starts before
xyz.openbmc_project.Software.BMC.Updater.service, and verify it
mounts alt-rofs for dual image systems.
The alt-rwfs will be mounted by the needed service in future
commits.
