This commit fix#150
Prior to this older versions of evobackup without `VERSION=` in them
would be treated as not having any exclude whatsoever as the `else`
block was only inside of the `if grep -q "^VERSION="
"${evobackup_file}"` block.
Now the treatment of old evobackup scripts is done if there isn't a
`VERSION=` in the script or if the version is older than 22.12.
