Hey, if backupmenu worked, you could have used it's recovery console to fix it without connecting to another machine

For the thing itself - the fastest solution is to enable swap on sd for a moment, delete eMMC swap partition, then re-create it at the end - mentioned 63 MB will end up *before* swap, so yoiu can quickly resize mmcblk0p2 to contain it. Or do so from early shell (backupmenu's one, or recovery shell, or...), when you don't need swap at all (nor have one mounted, so you can mess with it's partition without worry about disabling swap).
